Conjugating regular -ER verbs (Present tense) 1

-er verb present tense endings — Regular -er verbs follow: -o, -es, -e, -emos, -éis, -en. Using comer: como, comes, come, comemos, coméis, comen. The yo form is the same as -ar verbs (-o), but all other forms use e where -ar verbs use a. This vowel shift is the key difference.

Common regular -er verbs — comer (to eat), beber (to drink), leer (to read), correr (to run), vender (to sell), aprender (to learn), comprender (to understand), responder (to respond), prometer (to promise), depender (to depend), creer (to believe). Note: leer has an irregular gerundio: leyendo.

-er vs -ar endings in one sentence — A common exercise pitfall: mixing up -ar and -er endings. Remember: él habla (-ar, ends in -a) but él come (-er, ends in -e). If you write él coma, that's the subjunctive — a completely different mood. Getting the basic ending right is the foundation of Spanish conjugation accuracy.
