Singular must go with singular and vice versa for plural.

However, Grammarly mentioned one sentence as correct and other as incorrect. Please check the below two sentences.

  1. I usually post questions on this website.
  2. I usually posts questions on this website.

Subject: I. (Singular) Verb: post (this also need to be singular), so posts

However, "posts" is shown as incorrect on Grammarly. Why post? It is plural.

  • The subject-verb agreement rules apply to all personal pronouns except I and you, which, although SINGULAR, require PLURAL forms of verbs. Feb 10 '18 at 19:31
  • I often hear you was in American rap songs but I think it's non-standard. I don't think it's ungrammatical though.

As Lucian Sava said in the comment, the first person singular pronoun I and the second person pronoun you are peculiar in that they have their own subject-verb agreement rules.

I always requires a plural verb although it's logically singular.

I usually post (NOT posts) questions on this site.

But it has its own special form of BE, am.

I am (NOT are) posting a question.

The past tense of am, however, is was—not were.1

I was (NOT were) about to post a question.

You, on the other hand, always takes a plural verb regardless of whether it's plural or singular.

You post (NOT posts) a question.

1 It's possible to use were, but only when the proposition expressed is hypothetical or irrealis: e.g., If I were to post a question, I would think twice because it might get downvoted.
