GENES in Spanish: GENES

Written by Sofia Ramirez, Lead Spanish Curriculum Editor · Reviewed May 2026

Genes · noun · HEH-nehs

Genes in Spanish is spelled identically to English but pronounced differently — with a Spanish 'g' before 'e' sounding like the English 'h.' This biological term refers to the units of heredity carried in DNA, and while the spelling is a perfect cognate, the pronunciation difference (HEH-nehs vs. English 'jeenz') catches many learners off guard.

HEH-nehs

Los genes determinan muchas de nuestras características físicas.

Avoid These Mistakes When Using Genes

Pronunciation Error

Incorrect: Pronouncing genes as 'jeens' (English style).

Correct: Pronounce genes as 'HEH-nehs' with Spanish g sound.

In Spanish, the letter g before e or i makes a throaty 'h' sound, not the English 'j' sound. This is crucial for being understood.

Confusing with Jeans

Incorrect: Mis genes favoritos son azules.

Correct: Mis jeans (or vaqueros) favoritos son azules.

Genes (biology) and jeans (pants) are homophones in English but completely different words in Spanish. Jeans for pants keeps the English spelling or uses vaqueros/pantalones de mezclilla.
