The English term "man" is derived from Old English mann. The Old English form had a default meaning of "adult male" (which was the exclusive meaning of "wer"), though it could signify a person of unspecified gender. The closely related "man" was used much as the Modern English "one" (e.g., "one reaps what one sows"). The Old English form is derived from Proto-Germanic mannaz, "persona", which is also the etonym of German Mann "man, husband" and man "one", Old Norse maðr, and Gothic manna. According to Tacitus, the mythological progenitor of the Germanic tribes was called Mannus. The Germanic form is in turn derived from the Proto-Indo-European root manu-s "man, person", which is also the root of the Indian name Manu, mythological progenitor of the Hindus.
Age and terminology
The term manhood is used to describe the period in a human male's life after he has transitioned from boyhood, having passed through puberty, usually having attained male secondary sexual characteristics, and symbolises a male's coming of age. The word man is used to mean any adult male. In English-speaking countries, many other words can also be used to mean an adult male such as guy, dude, buddy, bloke, fellow, chap and sometimes boy or lad. The term manhood is associated with masculinity and virility, which refer to male qualities and male gender roles.
