Take out my second letter, and you get a crispy sandwich ingredient. Or the last name of a famous eighties dancing man. As a whole, I’m something that’s used as a signal for directing or warning. I’m usually quite bright!

My first four letters can be hard to swallow My two last letters is an onomatopea when you're hurt My whole is a feathery comfort

Hark, thou humble orb that dost hold secrets untold, encased in alabaster, thou art life's own mold. From thee springs the dawn of myriad forms, a fragile fortress in which something small warms

An iron rod that stirs a fire; A game where luck meets skill. I help to keep the flame alive; You’ll bluff when cards don’t thrill.

If you take away one hand, some will remain.
