Morphology

temperamental + behavior

The phrase is a straightforward adjective+noun composition: 'temperamental' (prone to sudden mood changes) modifies 'behavior', so the combined meaning "behavior marked by unpredictable or sudden changes in mood" is directly derivable from the constituents. This follows standard compositional patterns found across languages, so a B1 learner who knows both words would readily understand it.

Etymology

The phrase temperamental behavior comes from the word temper, which meant a person's mood or nature. Think of a small fire that suddenly flares up and then goes out—that image shows sudden mood changes, so the phrase means 'unpredictable or sudden changes in mood or attitude'.
