Niceness.

Just noticed I have 2 posts in a row calling something "nice."

I have a "nice" tag, you know.

My favorite one is "My 2 favorite 'nice' songs." [ADDED: I redid the poll.]

And "When you're nice to someone else... that someone else is nice back to you, and suddenly two people feel good about themselves and each other, and spread their feelings."

"Nice" is an interesting word. As the (unlinkable) OED puts it:

The semantic development of this word from ‘foolish, silly’ to ‘pleasing’ is unparalleled in Latin or in the Romance languages. The precise sense development in English is unclear. N.E.D. (1906) s.v. notes that ‘in many examples from the 16th and 17th cent. it is difficult to say in what particular sense the writer intended it to be taken.’

The meaning "Kind or considerate in behaviour; friendly (towards others). Freq. in to be nice (to)" only goes back to the early 1800s. Example from F. Scott Fitzgerald, This Side of Paradise i. i. 38   "I'm tired of being nice to every poor fish in school." But the way I used it in the previous 2 posts is the meaning "Delicate or skilful in manipulation; dexterous," which goes back to the 1600s. Here's the poet John Donne, writing in 1633:

So kiss good turtles, so devoutly nice
Are priests in handling reverent sacrifice,
And such in searching wounds the surgeon is,
As we, when we embrace, or touch, or kiss.

Turtles... fish...
