'Gorilla' is the large African ape; 'guerrilla' is an irregular fighter or the tactic of unconventional warfare.

Side-by-side comparison

Gorilla
noun

"Gorilla" is the largest primate, native to Africa. It is an animal with no relation to warfare.

  • Mountain gorillas are critically endangered with fewer than a thousand individuals remaining.

  • A male silverback gorilla can weigh up to two hundred and twenty kilograms.

  • Researchers spent years living near gorilla groups to understand their social structure.

Guerrilla
noun / adjective

"Guerrilla" describes irregular warfare or fighting carried out by non-conventional groups. Also used as an adjective: "guerrilla marketing" = unconventional marketing.

  • Guerrilla warfare relies on speed, surprise, and knowledge of local terrain.

  • The startup used guerrilla marketing to gain attention without a large advertising budget.

  • Guerrilla tactics were effective against the conventionally organised opposing forces.

Common mistake

"The gorillas attacked from the jungle" could mean the apes or the fighters: only context clarifies. "The marketing guerilla approach" is wrong: the unconventional tactic is "guerrilla marketing". Double R in "guerrilla".

Trick to remember it

  • •"Gorilla" has one R: simple and solid like the animal.
  • •"Guerrilla" has a double R and comes from a word meaning "little war", so it is the longer, more complex word, like irregular warfare.

Quick rule

  • •Is it the large African ape? "Gorilla".
  • •Is it the irregular fighter or unconventional tactic? "Guerrilla".

Did you know?

"Guerrilla" comes from a word meaning "little war" and entered English during the Peninsular War (1808-1814), when local fighters resisted the French occupation with irregular tactics. In 1984, Jay Conrad Levinson popularized "guerrilla marketing" for low-budget, high-impact campaigns. "Gorilla" has its own old story: the explorer Hanno the Navigator, in the 5th century BC, described a tribe of hairy people he called "gorillai", and the name was later given to the great ape.
