False Friend
A false friend is a word that looks or sounds similar across two languages but differs in meaning, leading bilinguals or learners to assume a correspondence that is not there. The term is a calque of French faux ami, coined by Koessler and Derocquigny in Les Faux Amis ou les Trahisons du Vocabulaire Anglais (1928). Spanish embarazada (pregnant) and English embarrassed, French librairie (bookshop) and English library, and German Gift (poison) and English gift are textbook cases.
False Friends vs False Cognates
The two terms are often conflated but are not synonymous. A false cognate is a pair that resembles each other by accident: similar form, no shared etymology, no historical relation. False friends form a wider class and include both false cognates and genuine cognates whose meanings have diverged.
| Term | Etymological link | Meaning correspondence |
|---|---|---|
| Cognate | Yes | Yes |
| False friend (semantic) | Yes | No or partial |
| False cognate (chance false friend) | No | No |
English pretend and French prétendre (to claim) share Latin praetendere and are genuine cognates, yet they mislead learners. Japanese arigatō and Portuguese obrigado both mean thank you but share no history; their resemblance is coincidence, making them a famous false cognate pair without misleading anyone semantically.
Chamizo-Domínguez's Classification
Chamizo-Domínguez (2008) distinguishes two main types:
- Chance false friends (false cognates): forms accidentally similar, no shared origin, no semantic overlap. They behave like cross-linguistic homonyms.
- Semantic false friends: forms genuinely related etymologically, with meanings that have diverged through specialisation, generalisation, metaphor, metonymy, or euphemism in one or both languages. These behave like cross-linguistic polysemes and often retain partial overlap.
The semantic class is the more dangerous one in practice because partial overlap encourages learners to extend L1 senses into the L2 incorrectly. English actually and Spanish actualmente (currently) overlap in their shared Latin origin but diverge in current sense; the partial familiarity invites confident misuse.
Why They Cause Errors
False friends produce reliable negative transfer because the surface similarity activates the L1 lexical entry and its semantics during L2 processing. Experimental work shows learners take longer to translate false friends than non-cognates and produce more errors with them. The N400 component in event-related potentials is enlarged for false friends, indicating semantic conflict at the millisecond scale.
In ELT
False friends are predictable enough to be teachable. Vietnamese English learners face a substantial false-friend inventory inherited from the French colonial layer, where Vietnamese kept the French sense while English carries a different one. Sympathique (Vietnamese borrowing influence) versus English sympathetic (compassionate, not "nice/agreeable"); actuellement / actual / thực tế / currently tangles. Newer English-origin loans in Vietnamese can also drift, with PR in Vietnamese often meaning self-promotion or showing off rather than the English public-relations sense.
Useful teaching moves include explicit lists of high-frequency false friends for the L1-L2 pair, contrastive minimal-pair work that shows where senses match and where they diverge, and reception tasks (translate from L2 into L1) that surface where learners over-extend. Treating false friends as predictable hazards rather than incidental errors lets teachers front-load the warning before the error becomes fossilised.
