To stare at someone in a lecherous or inappropriately sexual way; or as a noun, a person who does this.
From Middle English 'lichen,' possibly related to Old English 'licgan' (to lie down) or Old Norse 'lekkja' (to flame/burn). The verb form emerged in the 1500s with clearly sexual connotations. Some etymologists connect it to 'licentious' (unrestrained), though this is debated.
The word 'lech' is one of the few English words that manages to be simultaneously a verb and a noun referring to the same act and actor—you can 'lech' (verb) and be a 'lech' (noun)! Interestingly, it's primarily found in British English, where American English speakers more commonly use 'leer' or 'pervert.'
Etymology unclear but semantically gendered: 'lecher' (one who lechs) is traditionally applied to predatory men, though the term can neutrally describe sexual coercion. The gendering reflects historic power imbalances where male sexual coercion was normalized.
Use 'lech' neutrally when discussing predatory behavior, but avoid allowing the term to imply only men behave this way; recognize that coercion is a behavior regardless of gender.
["coerce","prey on","sexually harass"]
Naming sexual predation without gendering it strengthens accountability frameworks that protect all people from coercion.
