Very thin and lean, or to make something smaller or reduce in quantity.
From Middle Dutch 'slim' meaning 'bad' or 'cunning,' which shifted to mean 'slender' by the 17th century. The modern sense of physical thinness developed in English around the 1600s, possibly influenced by the idea of something bad being reduced or minimal.
The word 'slim' has a wild history—it started meaning 'cunning' in Dutch, then became an insult (a 'slim' person was sneaky), but somewhere along the way English speakers decided it sounded like something thin and graceful, completely flipping the meaning! Language evolution doesn't always make logical sense.
