The small plastic or metal sheath at the end of a shoelace that prevents it from fraying.
From French 'aiguillette' (small needle), diminutive of 'aiguille' (needle), from Latin 'acus' (needle). Everyone knows what this IS but almost nobody knows what it's CALLED.
You've used these EVERY DAY of your life and never knew the name! The little plastic tip on your shoelace is an AGLET! Now you know, and you'll think about it every time you tie your shoes forever! 👟😄
