Did you know?
'Guerrilla' comes from Spanish 'guerra' (war) + diminutive suffix — 'little war'. The word entered English during the Peninsular War (1808-1814) when Spanish fighters resisted Napoleon using unconventional tactics. 'Guerrilla marketing' was coined by Jay Conrad Levinson in 1984 for high-impact, low-budget campaigns. 'Gorilla' traces back to the 5th century BC: Greek explorer Hanno the Navigator described 'hairy wild people' on the African coast that local interpreters called 'gorillai'. The modern scientific name Gorilla gorilla preserves this ancient term.
