Usage notes

Many style guides and editors recommend the spelling come for verb uses (to orgasm/to ejaculate) while strictly allowing the spelling cum for the noun (semen/female ejaculatory discharge). Both spellings are sometimes found in either the noun or verb sense, however. Others prefer to distinguish in formality, using come for any formal usage and cum only in slang, erotic or pornographic contexts.
