I have two attitudes toward languages:
- I wish I knew it.
- I wish I knew it better.
Few experienced programmers would say that "X is the Best Programming Language" without going on to say what it is best for. I doubt that there are many programmers using Ada to put up web sites, and I very much hope there are none writing avionics software in PHP. In the natural languages one may have to search further to find this level of discrimination. Fortunately, Max Beerbohm gave us the Duke of Dorset:
He wrote mostly in English prose; but other modes were not infrequent. Whenever he was abroad, it was his courteous habit to write in the language of the country where he was residing--French, when he was in his house on the Champs Elysees; Italian, when he was in his villa at Baiae; and so on.

In his sterner moods he gravitated to Latin, and wrought the noble iron of that language to effects that were, if anything, a trifle over-impressive. He found for his highest flights of contemplation a handy vehicle in Sanscrit. In hours of mere joy it was Greek poetry that flowed likeliest from his pen; and he had a special fondness for the metre of Alcaeus. And now, too, in his darkest hour, it was Greek that surged in him--iambics of thunderous wrath such as those which are volleyed by Prometheus. But as he sat down to his writing-table, and unlocked the dear old album, and dipped his pen in the ink, a great calm fell on him. The iambics in him began to breathe such sweetness as is on the lips of Alcestis going to her doom. But, just as he set pen to paper, his hand faltered, and he sprang up, victim of another and yet more violent fit of sneezing. Disbuskined, dangerous. The spirit of Juvenal woke in him. He would flay. He would make Woman (as he called Zuleika) writhe. Latin hexameters, of course. An epistle to his heir presumptive... "Vae tibi," he began, "Vae tibi, vae misero, nisi circumspexeris artes Femineas, nam nulla salus quin femina possit Tradere, nulla fides quin"--
