At, By, For / Correct and Different Use of Prepositions

In English, prepositions are used with certain nouns in some expressions (phrase) and this does not change. The correct use of these expressions provides richness of speech. It shapes spelling in written language.

The following examples may gain a meaning other than their normal meaning. For example, we have learnt that “at” is a preposition of time: at 10.00, at lunch, at that time. Likewise, ” in ” was used for times such as years and months. In this lesson you will see different uses.
