Word selection

Some words are frequently misunderstood or confused by students.


In English, there are two sorts of articles: definite (the) and indefinite (a/an). It’s crucial to pick the proper one to go with a noun. Single, multiple, and uncountable nouns have various rules.


Prepositions express the relationships between sentence parts (e.g. in, on, to, by, of, since). They can be used to explain time, location, direction, and a variety of abstract and logical connections.

In English, there are many different prepositions, and many of them have many meanings. Reading and practice are the only ways to learn them all.


Pronouns are words that act as noun substitutes (e.g. they, it, him, this). Make it clear which noun you’re referring to at all times.

In academic writing, avoid using second-person pronouns (you, yours). Depending on the discipline and type of document, first-person pronouns (I, we) are sometimes appropriate.


Conjunctions are words that link the pieces of a phrase together. There are various forms of conjunctions, each with its own set of functions and restrictions.
