Stage 4: Grammar menu

These are the grammar topics that were tested in the Stage 4 PreQuiz.

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".

Abbreviations

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

WhoWho 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.
