Grammar · Verb endings
-다, the dictionary form and the stem
Pattern
[stem] + 다
Every verb and descriptive verb is listed in the dictionary ending in 다: 먹다, 가다, 크다. Take away 다 and what is left is the stem (먹, 가, 크), and every ending in this list attaches to the stem. The dictionary form itself is almost never said in conversation.
The mistake to avoid
Do not say 먹다 to mean 'I eat'. A sentence needs an ending, and for everyday speech that is -아요/-어요.
