Split infinitives

The "to infinitive" is a verb made up of "to" + the base form of the verb, like "to sleep". This lesson discusses the debate about whether a modifier is allowed to split the infinitive, as in "to quietly sleep".


This lesson is about the correct use of capital letters when making abbreviations.

Comma splice

Comma splices (also known as run-on sentences) are a frequent error in student writing, but they're easy to fix. Find out how in this lesson.

Who or whom

Who and whom are relative pronouns. One represents the subject of the sentence and the other the object. Never get them muddled again.

Sentence fragments

Sentence frags are also called incomplete sentences, usually meaning that the sentence has no dominant verb.

Confusing Words

they're, their, or there?

They all sound the same, but they have different roles in your sentences.

brought and bought

One is the past of 'bring' and the other is the past of 'buy'

than or then

One is for comparing things and the other is for signalling sequences.

affect and effect

One is a verb and the other is a noun (meaning that they behave differently in the sentence).

accept and except

One means "to agree to something" and the other means "not including something"

whose or who's

One is asking about ownership while the other is asking about identity

loose and lose

The first is about when something is about to fall off, and the other is when that thing can never be found again

past or passed

One means to travel beyond something, and the other is about being successful in your exams.
