When to Use a Comma with 'SINCE'

When starting a sentence with the word "since", add a comma after the first clause (group of words containing a subject and a verb).

Comma Use With 'WHILE' and 'WHEREAS'

When using "while" or "whereas" at the beginning of a sentence, place a comma after the first clause. In the middle of a sentence, place a comma before "whereas".

When to Use Commas in a 'DESPITE' Sentence

If "despite" (or "in spite of") comes at the start of the sentence, use a comma to separate the phrase starting with "despite" from the rest.

Comma Use in 'WHEN' Sentences

If you start a sentence with the conjunction "when", add a comma after the first clause. The comma is generally unnecessary if the when-clause is the second clause of the sentence.

How to Use Commas With 'IF'

If a sentence starts with an if-clause, add a comma after the if-clause. Do not use a comma when the sentence starts with the main clause.

When to Use a Comma Before or After 'Too'

In the middle of a sentence, we normally use commas to set off the word "too". It is not necessary to place a comma before "too" at the end of a sentence.

Comma Use Before and After 'By the way'

Wherever the expression "by the way" comes (at the start, in mid-sentence, or at the end of a sentence), it must be separated by commas or other proper punctuation marks, such as a period, a semicolon, or an em dash.
