Learn English – What’s the better preposition to use with “love” — “love for” or “love of”

"Simply put, a preposition indicates a relation between things mentioned in a sentence."

For example, in the above sentence, between is a preposition. There's the noun "relation", and the noun "things". The word "between" introduces a relation between them.

Wiktionary defines "preposition" as follows:

A closed class of non-inflecting words typically employed to connect a noun or a pronoun, in an adjectival or adverbial sense, with some other word: a particle used with a noun or pronoun (in English always in the objective case) to make a phrase limiting some other word.

Merriam-Webster says:

Definition of PREPOSITION: a function word that typically combines with a noun phrase to form a phrase which usually expresses a modification or predication

If you are still not quite sure what that all means, there's a list of English prepositions over at Wikipedia.

Also, as Kosmonaut points out in his comment, prepositions usually come before the words they modify — hence the name, "pre" + "position". However, note that there are mechanisms in place that allow prepositions to be "detached" from the words they modify; see, for example, these questions:

• How to combine in a sentence two verb + preposition pairs that have the same object?
• When is it okay to end a sentence in a preposition?

Overview

This is a conjunction of over and view suggesting the view from a high place where one can look over nearby obstacles to see the whole surrounding context. It uses, as a metaphor, the visual meaning of view (rather than it's meaning as a synonym of opinion for example)

We most often use of with view so this carries across to overview. Sometimes we use into with view but this isn't appropriate here because an overview isn't concerned with looking primarily at detail inside something.
