I'd is short for I would, or I had. In English, an apostrophe can mean 'letters are missing here'. So - you need to work out which letters are missing. In the examples you gave, the letters would be missing after the 'd', not before, which is where the apostrophe is. I'm = I am. the apostrophe is short for a I've = I have. the appostrophe is short for ha Does that make sense?

"I'd" is a contraction but it can be used for both 'I had' and 'I would'. I'd go on a diet if I were you. (I would) I was sure I'd seen him before. (I had) You know form context and grammar which word is represented by 'd.

You'd ;) be better to write What does I'd mean? Also I'm so confused.

I would. I'd like to go home. I would like to go home.
