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 – 12 of them covered here.

Before we jump into the first group of prepositions, let me briefly explain how this post is organized:

  • Each group starts with explanation – and plenty of examples – of how the prepositions are used and ends with a short quiz for you to practice what you learnt in that group.
  • Most prepositions are used in ways other than their most common use. In this post, in each group, I’ve first covered the main use, followed by other usages.
  • Many times, prepositions have been presented in tabular form for easy comprehension.
  • Comments are in blue font in square brackets (just like this) so that you can easily spot them.
  • Examples find place in the tables as well as bullet points (outside the table).
  • Prepositions can be broadly classified as prepositions of time and place. Wherever applicable, each group heading contains this information in square brackets.

If you want to practice exercises and learn other grammar rules, you may have a look at exercises on prepositions and subject-verb agreement rules.

Without further ado, let’s start with the most common group.

From…toByUntil/ Till

[A simple representation: by + time A]‘Until’ is used to show a situation that continues up to a particular time in the future. [A simple representation: until + time A or a condition]

‘Since’ is used to describe continuation of time from a fixed point in the past to present.
