Conjugating ar verbs present

Stem-changing -ar verbs keep the regular endings and mutate the stressed vowel in yo, tú, él and ellos only, because those are the forms where the stress lands on the stem. Nosotros and vosotros keep the original vowel. Three patterns cover the top thousand, and jugar is the only verb in Spanish that does u to ue.

Drop the -ar and add -o, -as, -a, -amos, -áis or -an. The ending says who is acting, so the pronoun is usually left out: hablo on its own is I speak. Mirar, necesitar, pasar and most other -ar verbs copy hablar exactly.
