Someone whose job is looking after pigs. This is an old word, and knowing that it is old is most of knowing the word. You will meet it in fairy tales, in Bible stories, in translations of Hans Christian Andersen, in anything set hundreds of years ago — the poor swineherd who turns out to be a prince. Nobody on a modern farm calls themselves this; they say pig farmer, or they work at a pig farm. So the word tells you about the world of the story as much as about the job: a world of villages, of animals kept out in the open, of low-status work. 'Swine' itself is the old word for pig, now used mostly in books, in the phrase swine flu, or as a rude name for an unpleasant person. 'Herd' here is not the group of animals but an old word for the person minding them, the same one hiding inside 'shepherd', who minds sheep.

牧豬人、養豬的人（古語，多見於童話與舊時故事；現代說 pig farmer）
