Synonym discussion
Sense: adjective/1
All five words describe an absence of humour or lightness, but they differ in tone and context. 'Humourless' is almost always critical — it implies a person lacks joy or cannot appreciate fun. 'Serious' is neutral and much broader, covering everything from a thoughtful expression to a grave situation. 'Solemn' suits formal or ceremonial contexts, carrying dignity rather than fault. 'Dour' suggests a stubborn, unfriendly harshness, often linked to disapproval. 'Grim' can refer to a specific mood or outlook ('a grim expression') rather than a fixed personality. A humourless colleague might refuse to join a game, while a solemn colleague would simply stay quiet during a moment of respect.

Etymology
Formed from 'humour' (the quality of being amusing or the ability to perceive it) plus the Old English suffix '-less', meaning 'without'. 'Humour' itself traces back through Old French to Latin 'umor' (moisture, liquid) — in medieval medicine, bodily fluids (humours) were believed to affect personality, so the word shifted from 'fluid' to 'mood' to 'ability to find things funny'. 'Humourless' has been in use since the early 19th century.
