1858: carpenter: no 'carpent' Jan 16, 2020

If a cleaner cleans, and a writer writes, does a carpenter carpent?—No. There are many words for which no parsing is possible anymore, but in these case there isn't really a historical form either. In the case of 'carpenter', it comes via Old French from the Latin 'carpentarius (artifex)' meaning 'carriage (maker)'. This makes 'carpenter' related to 'car' and even 'horse'.
