Synonym discussion
Sense: adjective/1
These words all describe someone whose emotional state is difficult to deal with, but they focus on different aspects. Moody (B1) is the most general — it means emotions shift quickly, often for no clear reason. Temperamental (B2) suggests that this changeability is a deep part of a person's character, almost like a machine that works only sometimes; artists and creative people are often called temperamental. Irritable (B2) is narrower — it means easily annoyed or angered by small things, without the idea of quick shifts between emotions. Sulky (B2) is more specific still: a sulky person is silently bad-tempered, often in a childish or resentful way that shows on their face. Unpredictable (B1) is the broadest of the four and can apply to behaviour, weather, or outcomes — not just moods. For example: 'Joon is moody in the mornings but fine by lunchtime' (quick emotional shift). 'The lead singer was temperamental and often cancelled rehearsals' (deep-rooted sensitivity). 'The waiter was irritable after a long shift' (easily annoyed). 'The child sat in a sulky silence after being told no' (silent resentment).

Etymology
Comes from Old English 'mōdig', meaning 'brave, proud, or high-spirited', which came from 'mōd' (mind, spirit, courage — the root of modern 'mood'). Over centuries the meaning shifted from 'brave' to 'angry' to 'easily changing in mood'. The sense describing atmosphere (modern sense 2) developed in the 1800s as people began using the word for art, lighting, and places that evoke a strong emotion.
