Usage

See contraction.

Verbs beginning with re- indicate repetition or restoration. It is unnecessary to add an adverb such as back or again : This must not occur again (not recur again ); we recounted the votes (not recounted the votes again , which implies that the votes were counted three times, not twice)

Re , in contexts such as re your letter, your remarks have been noted or he spoke to me re your complaint , is common in business or official correspondence. In general English with reference to is preferable in the former case and about or concerning in the latter. Even in business correspondence, the use of re is often restricted to the letter heading
