A question of clarification

If to enunciate means to speak clearly, is there an equivilent for thinking similarly?

My good friend Ann O and I have been pondering this, and not coming up with any good answers, so I'm asking all of you!

Free to a good home

In cataloging our books, we found we have five duplicates:
The Hour of the Gate, by Alan Dean Foster
Starseed, by Spider and Jeanne Robinson
The Callahan Touch, by Spider Robinson
Dreamweaver's Dilemma, by Lois McMaster Bujold
The Hugo Winners (Volumes I and II), edited by Isaac Asimov

These are available to a good home, if anyone would like. If there are no takers, we'll probably take them for credit to the used book store, but I wanted to offer them to friends first.
