2381: camp Jun 25, 2021
The word 'camp' relating to an open field for lodging is not so surprisingly the same as would be found with 'campus', but neither of these have the explicitly militaristic use that was once seen. While French for instance also has the word 'champ' (field), the root in Latin and then Old English had the sense of "contest; battle" hence phrases like 'camp-fever'. This is also related to the Old High German 'hamf' (paralyzed; maimed). Even in the 19th century, when the word 'camp' had moved on from militaristic senses, it took on religious ones as in 'followers of a doctrine', a sense still seen in reference to ideological battle, including secular academic ones. The sense of 'camp' as a hobby or sporting activity was developed from its use for military but it by a historical framework relatively new.
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'.
