2377: moustache, mandible, & kemp Jun 21, 2021
The word 'mustache' (or 'moustache') has been the word for the hair above the upper-lip since the 16th century, from French but ultimately the Ancient Greek μύσταξ (mústax) meaning 'upper lip'. This in turn is from the root *mendʰ- (to chew) thereby connecting this word to 'mandible': an animal's jaw bone, as well as the French 'manger' (to eat). Before this, English used the word 'kemp'—itself related to 'chin' and more surprisingly, 'camp'. In Middle English, 'kempe' referred to coarse hairs but is not related to other words like 'comb' or 'unkempt'.
