In the current times, the word needle is very polarising.

Will you have the vaccine, or not.  Is one of the reasons simply because you hate needles?

I know I do and have a fear factor of 100%.  Fortunately, I got very sick a few years ago and spent 10 days in the hospital, and was forced to have multiple needles every day.

Now it's not so hard

But, I digress.

A needle is one of those things used in the medical profession mainly to deliver vaccines and medicine.  It is a very small cylinder.

A needle can be used to sew up a garment or make repairs.  This is a smallish piece of metal with an eyelet.

A needle can also be used to stitch up wounds, though it's best you have a local anesthetic first.

Another way of using needles is to describe tiny icicles which hurt when they hit your face or your eyes.  It is called a needle effect.

Then, another use of the word, is to needle someone, that is to say, bombard them with questions, or annoy them.

It's a pointer on a dial, like that of a fuel gauge, which for me, always seems to hover just above empty.  It can also be on a compass, where heading north is not always clear especially where magnets are nearby.

A fir tree's leaves are more like needles.

You need one to play a record on a gramophone, not that they exist anymore.

Paradoxically it can also be used to describe a pointy rock or an obelisk-like "Cleopatra's Needle"

It is also an etching tool.
