I have to explain everything to you!

to have something written all over it

to have a clean bill of health

have a pleasant flight

to have a shelf-life

to have in stock

to have strong feelings for someone

I have mislaid the letter.

have feet of clay

to have a clue

Have you got anything for travel sickness?

I have got a rash.

I have no more money in my wallet.

to have a short temper

to have in view

to have taken a wrong turning

to have blue balls

to have come to the right person

Have you read any good books lately?

to have a cold

to have a shot at something

I have succeeded.

to have serious intentions

to have no zest

I have no small change
