And such a twistedly fitting one at that! Oh, how oft I have felt this way:
Manque
(adjective)
[mawnKAY]
1. having talents or ambitions that are unrealized or unfulfilled; (used postpositively — placed after the word it qualifies): “Practical concerns diverted Yunee’s talents to programming, but she remained a poet manque at heart.”
Origin:
Approximately 1778; borrowed from French, from past participle of ‘manquer’: to fail; from Italian, ‘mancare,’ from ‘manco’: lacking, left-handed; from Latin, ‘mancus’: having a crippled hand, infirm, probably from ‘manus’: hand.
