When does one use a "s" at the end of verbs?
Wondering if you can put a "s" on any verb even in the formal "you" form. Or just on some?
You will find "s" on the informal you verbs in the present indicative. It is best to study the conjugations to see the patterns or to buy a big yellow 501 verbs book which is filled with not only the conjugated verbs but so many other tips and verb learning tools.
