A tribesman is a man who belongs to a tribe — a group of people who share the same ancestors, the same language and customs, and usually live together in one area under their own leaders. You meet this word mostly in three places: in writing about history (the tribesmen who fought against Rome), in news or travel writing about places where tribes still organise daily life (parts of Afghanistan, Papua New Guinea, the Amazon, parts of Africa and the Middle East), and in old adventure stories. It is not a word people normally use about themselves. A man from a tribe in Taiwan or in America would say 'I'm Amis' or 'I'm Navajo' — he would name his people, not call himself a tribesman. It is a word used from the outside, looking in. That is worth knowing, because in the wrong sentence it can sound old-fashioned, or as if you are treating people as a type rather than as persons, especially in older writing that treated tribes as 'primitive'. Careful modern writers often prefer 'a member of the Hazara tribe' or just the name of the group. The word itself is not rude, and journalists still use it, but it carries the smell of that older writing. The plural is 'tribesmen', and 'tribesmen' is also often used loosely for the fighting men of a tribe — armed tribesmen attacked the convoy.

部落男性成員／部族戰士。台灣講原住民族時，一般說「族人」或直接講族名（阿美族人、排灣族人），幾乎不會用「部落男子」這種說法；tribesman 多半出現在講外國、講歷史的文章裡。新聞裡的 armed tribesmen 常譯成「部族武裝分子」。
