I've posted a lot of nouns, but not many verbs or adjectives. Here's a list of verbs and adjectives pertaining to eating and drinking. As in English, there are a lot of subtle differences here -- I hope I get them at least close to correct!
borða (v.) - eat (see notes below)
bragða (v.) - taste
drekka (v.) - drink
éta (v.) - eat (see notes below)
girnilegur (adj.) - appetizing
ljúffengur (adj.) - delicious
óætur (adj.) - inedible
saddur (adj.) - full
súpa (v.) - sip, drink
svangur (adj.) - hungry
svelgja (v.) - swallow
svelta (v.) - starve
tyggja (v.) - chew
Most of the verbs are so-called "strong" verbs.
I think éta is less "formal" than borða, and is used moreso to talk about animals eating, whereas borða is used to talk about people sitting down at a table and eating.
[ Note from Ásta:
Dýr éta og menn borða. Animals eat and people (strictly speaking...men) eat..... I don't know how else I should translate this. My grandmother used to say this to me all the time when I was a kid. She grew up on a farm. I guess a lot of people who haven't lived on a farm don't make this distinction. I would never say: ,,Ég er búin að éta" = "I have already eaten." It sounds disgusting and rude. Under all circumstances I would say ,,borða" when referring to humans. ]
[ Another note from Ragnar:
[I]f someone consumes food in a very"animalish" way you can use "éta" about people but you SHALL always use "éta" about animals! ]
Éta is an irregular verb. Here is its conjugation:
I think this has come up on the list before -- but if you say "Ég er full(ur)" you are actually saying you're drunk. If you want to say you're full (of food), you should say "Ég er saddur/södd."
Whenever I learn new words, I try to use them in sentences. Usually, the sillier the sentence, the better I remember the word...
