Etymology is one of the few interests I managed to acquire at St. Custard's when in an early Latin class, our master 'Plum' Tucker wrote one word on the blackboard:
and then asked us how the word came about. We just sat there in our freezing Devonshire classroom, smelling of manure and Horlick's tablets, and then underneath he wrote two Latin words:
paene (almost) + insula (island)
and ecco! revelation. Thanks Plum, against all the odds something stuck.
