I didn't mean to be stuffy (not that I think you were being critical), just stating the fact that indices is the proper plural. I've seen dictionaries which include terms which have gained acceptance by common use. Sometimes I still don't acknowledge them as "proper". Maybe I've been working with computers and rigid syntax for too long...but it scares me that someday I'll look in a dictionary and see that it's now considered acceptable to axe someone a question.

Another one that really got me was a former boss who always called an index "an indices". (US born, native speaker of English.)

>I, too, have been of the somewhat stuffy, but satisfying, opinion that only "indices" will do. While I remain convince, my office mates did force me to stop ranting about this when they showed me a dictionary with both forms as valid. Alas.
