What’s motivated this micro-diatribe is that I would really like to know what gailr’s
de gustibus non est disputandum, suum cuique
means; her comments always seem thoughtful and erudite and I'm sure it's a zinger.
To atone for my own past Latin transgressions, I’ll herewith give as examples the two phrases I remember using on this site:
Post hoc ergo prompter hoc --> When two things occur in succession, the first caused the second; and
Fames optmum condimentum --> Hunger is the best spice
(That one I frequently used when my children were small and complained about what I served for supper).
In return, I’d be grateful if anyone could give the Latin version of “You can tell what a thing is by what it does”. It’s been too long ago when I learned the Latin phrase, which sometime thereafter failed to make the leap from one memory synapse to another; the fact that I have no trouble remembering that I used to know it provides not one whit of solace.
