I was in the elevator this morning when I heard someone say this, pertaining to the slowness of the elevator:
- “You must have patient.” (X)
Well, the thing is, he was not in the hospital when he said that. He was merely telling his friend to “be calm and wait”.
- patient (n.) – a person who is receiving medical care in a hospital or clinic
- patient (adj.) – be calm and without complaining
- patience (n.) – the quality of being patient
Since the above speech refers to a person’s “quality” because of the word “have”, a noun must be used instead.
- “You must have patience.” (√)
Compare with this:
- “You must be patient.” (√)
In general, you could say that a noun is used after “has/have”:
- … has intelligence
- … has beauty
