Please help me with some questions about the Konjunktiv II mood:

1. Is the sentence "Ich äße es" in the imperfekt or in the present tense? I ask because conjugate reverso says " "äße" is imperfekt (praeteritum), while descriptions on sites like linoglia imply it's in the present tense
2. Is the sentence "Ich würde es gegessen haben" a grammatically correct sentence? If so, is it in the Futur II tense?

• How would you translate it? My attempt at a translation would be "I would have eaten it", but this sounds like the translation for "Ich würde es gegessen haben" as well?
• is the sentence "Ich hätte es gegessen" in the plusquamperfekt or the perfekt tense?

Thanks!

I don't know how much exposition you need on me but I would like to live in Germany and maybe become a citizen at one point however I was wondering if any of you that know the language or learning other languages on your own have any pointers for me.
I'm a sophomore so I have years to become familiar with the language.
Duolingo has helped me become familiar with the extreme basics (Ein, eine, Mann, Frau, Junge, Mädchen, conjugations of trinken, essen, and sein)
I've tried Duolingo before but for me its easier to fall out of the routine of doing it easier than it is to do it.
My school also doesn't offer a German class for me to be a part of.
So I just wasn't sure if I just need to try it again and be more serious, I should try a different program because Duolingo just isn't that great, or what else I could do.
I apologize if I broke any of the rules (I tried to google translate them but its possible that I mistyped) and if I did then feel free to report and take this post down and if I explained somethings poorly.
I appreciate all help in advance!

Hi! I recently started to learn german on my own, literally three days ago. So, I took a complete grammar guide as a reference (maybe I took the hard way, idk) while I look up for another kind of textbook more suitable for my level. Well, in that guide, reading about how to conjugate verbs I bumped into a bunch of examples like essen, lässen... and here comes my doubt:
In this guide the 2nd person and 3rd person are conjugated this way:
du/esie/es ißt
du/esie/es läßt
BUT when I checked out on the Internet and LEO (ENG-GER dictionary app) they often are conjugated as "isst" and "lässt".
I know that phonetically are essentially the same sound, but I read about some subtleties pronouncing the previous vowel and I don't know if they are fully interchangeable or if they respond to a fixed orthographical rule.
I tried to do my homework but Google didn't work for me this time. Can anyone explain it to me, foolproof?
Thank you in advance!
PS: I'm new on reddit so if I did any mistakes at creating the post tell me please. Correct my english if necessary too.

Hey, I’m an American living in Germany for a few weeks. I have a really kind host family and want to thank them properly, but since I’ve only studied German for 4 years the grammar and conjugation are hard for me. I attempted to write this letter in english and in German and would greatly appreciate some help making the German sound better! I want it to sound like I wrote it so some things like, saying a phrase as an american would vs how a german would, are ok. I just would love help with spelling or grammar, things like that! Thank you guys so much ^u.
“English: Thank you so much for taking such care of me these 2 weeks. I was so nervous about livin with a new family in Germany, but you took me into your home so wholly that I never had anything to worry about. I always had plenty to eat, your house always felt like a second home to me, but most importantly I got to see what a few weeks into your life looked like. From meeting all of your brothers and sisters to having family days golfing and Kägling, and even just speaking in the morning in a language strange to me. For all your kindness and sympathy, and all of your help strengthening my language, I thank you. From the bottom of my heart. Sincerely, Kristian.
My attempt at german: Danken ihr do viel, für nehmen so gute Sorgfalt von mich diesen zwei Wochen. Ich war so nervös zu mit ein neue Familie leben mit, aber ihr nehmt mich inzu ihren Heimat so völlig, dass ich müsste kein sorgen gemacht. Ich hatte immer reichlich zu essen, ihren Haus füllte immer wie eine zweine Heim für mich, und meisten wichtig, ich blickte was eine Woche in ihren Familia sieht aus. Inklusive treffen mit ihren Brüder und Schwestern, Golfen und Kegeln zusammen, und nur mit mich jeden tag sprechen, in ein besonderes und anderen Sprache. Für alle ihren Hilf und Sympathie, und alle diene Hilfe mit meinem Deutsch verbessern, ich danke Ihr. Von die Hintern meine Herz. Herzlich, Kristian.”

So, I already did a post about the Umgangssprache but have gotten a lot of private messages with questions. You guy are amazing! So, here are some more phrases and words to use. Umgangssprache is the oral language and uses different words and a reduced grammar compared to the written language "Schriftsprache". As always the disclaimer: Ignore the typos please. And notice that there is not one and only Umgangssprache. Language is dynamic and it varies between regions and persons. But I think most would agree with me that you shouldn’t use these words with your boss – and there are different levels of Umgangssprache!

Words

abhauen: to bunk off, to run away “Hau ab” – Get lost!, “Die Party is wirklich langweilig, lass uns abhauen.” - The party is really boring let’s hit the road.
spinnen: you see the joke “I think I spider” a lot at the internet since the word has two meaning a) to spin b) to be bonkers “You spinnst doch” – You are crazy! (notice the use of doch!) PS: The sentence „Spinnen spinnen“ is a correct one.
chillen: One of many Anglicism. It is conjugate like a normal verb! Ich chille, du chillst, er chillt, wir chillen, ihr chillt, sie chillen But the only meaning is to relax. „Ich habe gestern nichts gemacht außer gechillt.“
Digga/Diggah/Digger: This is part of the so called „Assi“ or “Asi” language. If you want to aime for the rough uneducated gangster vibe. (No offense intended). It means the same as “Dude”, but I would prefer “Alter”.
Alter has many meanings: a) mein Altemeine Alte=my fathemy mother (derogative) b) age c) dude d) expression to show surprise - an old-fashioned phrase is “alter Schwede” – old Swede”
rausgehen: short form of “hinausgehen”, to go out of a building “Gehen wir raus zum Schwimmen?” Not to be confused with ausgehen! to go out to a party/date “Möchtest du mit mir mal ausgehen?” – Would you like to go on a date with me? “Ich gehe Samstags immer aus” – I always go partying on Saturdays
Daheim= synonym to Zuhause but with another connotation. It feels comfy. Notice that some people in Northern Germany do not use it. Use: Ich gehe heim. - Ich gehe nach Hause Ich bin daheim – Ich bin zu Hause. Daheim ist es am schönsten – Zuhause ist es am schönsten.
bescheuert/bekloppt: daft „Bist du komplett bescheuert?“ – Are you totally daft?
genau: a) precise b) exactly c) You are right! You will hear c) all the time. “Genau, das finde ich auch.”
hammer: amazing, super
krass: amazing
abgehen a) to miss someone: Hannah ist gerade im Uraub. Sie geht mir wirklich ab. b) to party very hard: Wenn ich viel Alkohol trinke, dann gehe ich total ab. Die Party geht total ab.
geiern: to look enviously on something like a vulture „Sie hat nie etwas zum Mittagessen dabei. Sie geiert immer mein Essen an.“
angepisst: pissed: „Ständig versetzt sie mich. Das pisst mich wirklich an.“
versetzen: a) recolate b) to not appear at a meeting: “Wir hatten ein Date, aber sie ist nicht gekommen. Sie hat mich versetzt.”
raffen: to get it/to understand something: “Sie versteht es einfach nicht – und sie wird es auch nicht raffen.“
checken: to get it/to undertsand sth.: „Checkst du es jetzt?”-“Ja, ich habe es gecheckt.“
Hä: impolite version of „What”/Was
Krass: incredible, rad
alle: a) Adv. everyone b) Adj. to be out of stock/empty: “Habt ihr noch eine Cola?”-“Cola ist heute alle.”
abhängen: to hang out
abschleppen: a) to tow a car b) to pick someone up (most of the times the word implies sex) “Ich habe gestern einen Typen abgeschleppt.”
der Typ: guy
Tja: ¯|_(ツ)_|¯ literally the answer to everything. It means: you cannot do anything about it even if you want.
nerven: to annoy someone: “Das neue Windowsupdate nervt mich.” “Meine Schwester nevt mich”

Phrases

nur so: by the way of conversation, without any intention “Magst du Anna eigentlich?” – Wieso fragst du? „Nur so.“ Do you like Anna btw? – Why are you asking? – No reason.
Mensch: do show that you are exasperated “Mensch Simon! Du bist schon wieder zu spät.!

In my case, English and Arabic are native and I know a bit of French. Will edit this as I remember more things.
English:
Helps:

• Vocabulary is mostly similar with a few spelling changes

Hinders:

• There are some false friends (bekommen was quite the hurdle at first!)
  
• Dative case was hard to get at first due to lack of it in English
  
• Genitive case is different in English (needs the genitive -s for masculine/neutral nouns and doesn't use a helping preposition like "of").
  
• Lack of present continuous tense can cause gems like "Ich gehe zu essen"
  
• When replacing a noun with "it", using a noun's gender instead of "es" (Still guilty of this one)
  
• y being pronounced u :(
  

Arabic:
Helps:

• The commonly difficult sounds "r" and hard "ch" exist in Arabic.
  
• Same counting system (One and twenty instead of twenty one)
  
• Uses definite article with days (German's "Ich sehe dich am Samstag" becomes "I'll see you on the Saturday" in Arabic as opposed to "I'll see you on Saturday" in English).
  

French:
Helps:

• Umlaut sounds have equivalents in French (ö is the French e and ü is the French u).
  
• Verbs are also conjugated depending on the pronoun pretty analogously to German.
  
• Le passé composé (used commonly to talk about past events) is constructed very similarly to the German Perfekt, even down to using the French equivalents of "haben" and "sein" as helping verbs (The French "sein" is also used for movement as far as I know. Might even be used for changes of state). Also, as in German, only the helping verb is conjugated (the participle remains unchanged).
  
• The royal "you" concept also exists in French (but it is the second person plural, not the third person plural, which makes more sense to me).
  
• French also has gendered nouns as well (although of course the Germans have to one up the French by having 3 genders instead of 2. Also, noun gender plays a far smaller role in French [for example, no case declinations] than it does in German).
  

It seems like in every language there are rules for conjugation that are broken for the most commonly used verbs. Or to say in another way: the most commonly used verbs are conjugated as "irregular" or "exception" cases. I'm just wondering if there's a historical reason.
English Example:
To Be becomes I am. <-- Am doesn't look at all like "Be"
French Example:
Etre becomes Je suis (to be) <-- Suis doesn't look at all like Etre Avoir becomes J'ai (have) <-- ai doesnt' look like avoir
German Example:
Sein becomes Ich bin <-- bin doesn't look at all like Sein Essen becomes Du isst (eat) Geben becomes Es gibt (to give)
Japanese Example: する becomes します (to do) <-- shimasu doesn't look at all like suru くる becomes きます (to come) <-- kimasu doesn't look at all like kuru
I'm only mentioning easy examples, but verbs like: to go, to come, to be, to have, and to do.
I bet each verb has it's own unique story as to why it ended up that way, but still it feels like the most common ones are always irregular.
My hypothesis, that has no evidence, is that these verbs are used the most so they changed the least and so we're using their old forms that don't necessarily follow modern conjugation rules. Or maybe it's the opposite and they changed the most.
Anyone have any ideas?

The prompt of my essay is to talk about stereotypical things German's may think that Americans do. If you could proofread my essay for spelling, grammar, or conjugation errors that's be wonderful. :)
Im Deutschland wohnt kein Amerikaner, so Leute wissen uns nicht. Deutschmann denken uns alles gross. Sie denken uns alle spielen basketball und Baseball gern. Wir essen nicht so viel esse! Deutschmann denken uns Schiessen Flaschen alle tag. Ich weiss ganz bestimmt, dass ist sicher nicht! Oh Deustchmann, Ihr seid wohl veruckt, aber Ich liebe dich immer noch!
