Her sense of humour always brightens up the room.
Humour → It originates from the Latin word 'humor' (meaning fluid or liquid), which was used in medieval physiology to refer to bodily fluids believed to influence temperament. The word evolved in Middle English to refer to a person's mood or disposition, leading to the modern sense of the term as a quality that evokes laughter or amusement.
Think of the original meaning of 'fluid' — just as bodily fluids were thought to affect one's mood, humour today refers to the quality that can change our feelings and make us laugh.
