The first rule is the most-commonly used rule on subject-verb agreement and will serve your purpose on most occasions. Second, I’ve underlined the subject and the corresponding verb in the examples throughout this post so that you can follow them easily.

Most people falter on prepositions when they face a situation where they can’t decide between two (or even more) prepositions that both seem to be the correct answer. Few examples of such commonly-confused prepositions: (1) over and above; (2) at, in, and on. And there are plenty more.

Prepositions are best learnt when you learn them in groups of such commonly-confused prepositions and not as individual prepositions. After all, that’s where you make most mistakes.

In this post, you’ll learn prepositions in such groups – 17 of them covered here.
