Practice / Personal Vocabulary

Look up food and drink words on leo.org, dict.cc and/or Beolingus. Concentrate on foods that you like, that you dislike or that you are allergic to. Make your own vocabulary list: On paper, on the computer, on the internet (e.g. leo.org) or, if you have Linux, use Parley. Include the German article (der/die/das for masculine/feminine/neutral) and the plural form. Practice the sentences above with various types of food and/or create short dialogs. You should both speak them and write them to remember them better.

Grammar/phrasing explanation: like, gern

In English liking or not liking something is expressed, well, with the verb "like". In German, however, the adverb "gern" is used. This does not only go for eating, but for everything:
Ich spiele gern Tennis.
I like playing Tennis.

Likewise, "prefer" is expressed with "lieber", an adverb roughly meaning "rather".
Ich trinke lieber Wein als Bier.
I prefer drinking wine over drinking beer. ("als" means "than")

Memorize: Pronouns

Try memorizing the pronouns. Concentrate on the singular ones for now.

Practice: Verb conjugation

Conjugate the verb "trinken" in all six forms. It does not change the root vowel in the present tense.

Now try to do it from memory for either essen or trinken or both.

Grammar/phrasing explanation: Negation of verbs

Negation is done with "nicht" = "not", not with a helping verb like "don't" or "doesn't".

nicht essen
ich esse nichtwir essen nicht
du isst nichtihr esst nicht
er/sie/es isst nichtsie essen nicht
not eat
I don't eatwe don't eat
you don't eatyou don't eat
he/she/it doesn't eatthey don't eat

Grammar/phrasing explanation: Questions

Just like negations don't use the helping verbs "don't" and "doesn't", questions do not use the helping verbs "do" and "does", either. Just invert the subject and verb to get a question.

Isst du Erdnüsse? - Do you eat peanuts?
Was isst du? - What do you eat?

Grammar: Conjugation of the verb "sein" (to be) - irregular

ich binwir sind

Now instead of practicing sentences about what you like or don't like, create sentences what your boyfriend/girlfriend/spouse/significant other likes or doesn't like, or your kids, parents, grandparents, friends, ... .
