Is it wrong to use a comma after "in addition" at the beginning of a sentence? [closed]

punctuation commas

Good question. "In addition", in addition to being a prepositional phrase (apologise for tautology), is an adjunct. Adjuncts, according to nearly all style manuals, should be set off with a (pair of) comma(s). Josh Friedlander has done poor research: The Chicago Manual of Style clearly says, "when clauses are very short and closely connected, the comma may be omitted", which, I suspect, is what you are referring to. I, personally, don't agree with it - as it makes rules much vaguer and less precise - but it is up to you decide whether to follow it or not; regardless of your opinion on it, though, a comma should always be placed after adjunct introductory phrases such as "in addition".


I always use a comma after "In addition."

I try to use a comma (or some other punctuation) when there is a significant pause, because that's what commas are for — to indicate a pause.

Other punctuation that can be used to indicate a pause are em dashes, colons, and semicolons. However, in the case of "in addition," you would only use a comma.
