I am first found in caves, now prolific online; I am a depiction, a drawing, a symbol, or sign. I will convey whichever mood you could wish; or for that matter, a fist, flask, or fish. What am I?

I welcome the day with a show of light, I stealthily came here in the night. I bathe the earthy stuff at dawn, But by noon, alas! I'm gone.

Who has married many women but was never married?

A father's child, a mother's child, yet no one's son.

Who am I?

Spelt forwards I’m what you do every day, spelled backwards I’m something you hate. What am I?

You see me once in June, twice in November, and not at all in May. What am I?

Your mother’s brother’s only brother-in-law is asleep on your couch. Who is asleep on your couch?

I make a loud sound when I’m changing. When I do change, I get bigger but weigh less. What am I?

I shave every day, but my beard stays the same. What am I?

I am 5 letters long.
My first two tell you who I am
My first 3 could be a medicine
My last three reversed could be a young boy.
My 4th, 3rd and 2nd in that order could be a fruit drink.
If you have me you may hang me round your neck
WHAT AM I ?
