Old English man(n), (plural) menn (noun), mannian (verb), of Germanic origin; related to Dutch man, German Mann, and Sanskrit manu 'mankind'
Traditionally the word man has been used to refer not only to adult males but also to human beings in general, regardless of sex. There is a historical explanation for this: in Old English the principal sense of man was ‘a human being’, and the words wer and wif were used to refer specifically to ‘a male person’ and ‘a female person’ respectively. Subsequently, man replaced wer as the normal term for ‘a male person’, but at the same time the older sense ‘a human being’ remained in use.In the second half of the twentieth century the generic use of man to refer to ‘human beings in general’ (as in reptiles were here long before man appeared on the earth) became problematic; the use is now often regarded as sexist or at best old-fashioned. In some contexts, alternative terms such as the human race or humankind may be used. Fixed phrases and sayings such as time and tide wait for no man can be easily rephrased, e.g. time and tide wait for nobody. Alternatives for terms such as manpower or the verb man exist: for example, staff or employees, and to staff or to operate.
