Verbs that end in a consonant “y” add “es” in the 3rd person singular and also change the spelling. The “y” is replaced with “I” and “es” is added.

​On the other hand, if the letter before “y” is a vowel, the verb adds “s” ending and, there is no spelling change. In both cases the number of syllables does not increase.

Remember:

To form questions, the word order changes. “Do/does” is used at the start, followed by the subject and then the main verb.

We also use “do/does” again in the reply.

Summary

To recap, we’ve seen that the present simple is used to make generalizations and talk about things that happen frequently, often together with adverbs of frequency (e.g., always, sometimes, never).

It uses the simple infinitive form of the verb, without “to,” e.g. “to work,” however, there are spelling and pronunciation changes when the subject is in the 3rd person, e.g. “he/she/it works.”

This is a very common tense and is found in media all around us.
