An OPERCULUM is one or another of these:

a) the focusing mechanism in the eyepiece used by jewelers for evaluating the quality of gemstones.

b) the muscle, directly beneath the vocal cords, which allows a singer to control vibrato

c) a duct in a living organism

d) the lid closing the aperture of various species of shells, such as the common whelk

e) a bag for carrying needlework, knitting, etc.

f) a small shrine

g) a brief musical work of second-century Rome, using voices and instruments

What's your pleasure, Folks?

I vote for D.... it just sounds right.

Kalleh asked me to vote on her behalf. She said if one of the daffynitions was medical, I should choose that. I therefore vote for b) on her behalf.

For myself, I vote for d).

d is d'answer for me.

OOh - I like them all!

I wish I had an operculum for my knitting . . . but I think it's really D. It must be D, right? I mean, since Arnie and Jo both voted for D?

Interesting that 2 of them involve music, eh? And the shrine idea is good, too. Sigh.

OK - D for me, too.

And what IS that thing the jewelers use?

I think everyone else is correct, so I'll join the
crowd for a change.
