I can be used as a bolt or pin. I can hang, fasten, or mark a thing. If you suggest me during intercourse, you might be admired or called the worst.

I'm an aviary type and yes my bones are hollow. At least my name carries no innuendo, like that little weirdo swallow.

I fit in sockets, and brighten the space, I sprout, then grow, then flower in place. A four-letter word, one few stop to think, Yet I live in the soil, and glow in a blink.

If you do me well, the price goes down. If you do me poorly, the seller wears a frown. I’m common in markets but rare in the mall. What am I?

I can be baked but I'm not bread. When I'm hot, people want to get rid of me. I'm a component in chip manufacturing but I'm not silicon. When there are many of me that are small, we're insignificant. When people sit on a couch, they can become a kind of me.
