Etymology

Origin of temperament

1375–1425; late Middle English < Latin temperāmentum due mixture, equivalent to temperā ( re ) to mix properly + -mentum -ment

Explanation

While a mood can change, your temperament is your overall tone most of the time. Just like dogs, people have temperaments: some are aggressive; some are playful; and some are just happy to carry your slippers. Just as a temperature gives a reading of how hot or cold something is, your temperament gives a reading of your disposition, or general outlook. Some folks with optimistic temperaments see that glass as half full; other more pessimistic folks see it as half empty. And there are still others who prefer to drink straight from the bottle.
