Finger tips to add "es" and "s" to an action verb to convert a base form into a third person singular form


Please let me know, when we should add es or s to an action verb to convert a base form into a third person singular form? I meant to ask are there any finger tips we can follow?


Examples:


go = goes


Walk = walks



Answer



Keep in mind that there are both regular and irregular verbs. If we just go by the examples you've provided, we could hypothesize that the "s" ending follows a (regular) verb root that ends with a consonant and "es" goes with a (regular) verb root that ends with a vowel--usually an 'o'. Verbs that end with 'y,' like "to fly" become "flies." Verbs that already end with an "e" just need an 's' to conjugate in the third person. I'd say that those are decent rules of thumb.
