Foible is one of those awkward words. Awkward in its voicing, in the sound of it, and in its meaning. I sat with the word for a bit, hoping for some poetry… but it’s not a word for which the lyrical comes running. (In the category of “Rhymes with Foible”: deubel, greubel, loibl, roybal. I’m not even going to bother looking those up.
It’s not even a word with very much oomph to it. A foible or two hardly makes one a sociopath or felon. On the contrary, unless they’re hurtful or malicious, it’s often the minor weaknesses and eccentricities which make for an interesting character.
