Having entirely opposite meanings

"Temper" is a bit strange word.

1)
One of its meanings is kind of "mood" or "feeling".
For example;
She is a good/bad temper.

2)
Other meaning is "calmness" or "composure".
For example;
He lost his temper.
He is keeping his temper.

3)
On the other hand, one more meaning is "anger" or "conniption fit".
For example;
She is in a temper.

2 and 3 are completely opposite. One word has opposite meanings...
I wonder if there is such a word in Japanese. Could be.
