estéril
/esˈteɾil/ · B2 · adj
sterile, infertile
🏜️ es-TÉRIL ≈ Latin sterilis, 'barren'; sounds like 'stare-ill' at empty land
Estéril comes from Latin sterilis, meaning barren or yielding nothing. Link it to English sterile, its direct cousin: a sterile place produces no life, and an estéril idea or effort produces no results.
