Words for things you didn't know have names

#1: Philtrum
Definition: the vertical groove on the median line of the upper lip



Example Sentence:
His chiseled features even included a well-defined philtrum.

Origin:
In Greek, the primary meaning of philtrum is "love potion" – which suggests that seductive powers were attributed to this facial feature.

#2: Ferrule
Definition: the protective point or knob on the far end of an umbrella.



Example Sentence:
He used his umbrella as a cane, and with every step planted its ferrule in the ground.

Origin:
Ferrule comes from the Latin viriola, meaning "small bracelet." This makes more sense when you consider that ferrule is also the term for the metal band at the end of a table leg (or similar object) that strengthens it or prevents it from splitting.

#3: Aglet
Definition: the tag covering the ends of a lace or point – e.g., the reinforcement at the end of a shoelace.



Example Sentence:
A missing aglet can make lacing one's shoes a challenge.

Origin:
Aglet indirectly comes from the Latin acus, "needle" – as does the word acute.

#4: Punt
Definition: an indentation at the bottom of a molded glass bottle



Example Sentence:
Pouring the champagne, she held the bottle with her thumb in its punt.

Note:
Although it remains a matter of debate, explanations for the function of the punt include strengthening the bottle and also reducing its holding capacity.
The alternative name for the punt is kick.
