The present simple form is used for verbs that express an action happening right now. It's also known as the –s form because the present simple form is made up of the base form plus –s.
Hey, we never said these verb forms had cool names. Actually, maybe we did. Sorry—we take it back.
P.S. If a verb ends in o, x, ss, sh, ch, or zz, add –es to the end to make the present simple form. When a verb that is more than one syllable ends in a consonant + y, you can make the present simple form by changing the y to an i and adding –es.
