diámetro

diameter

noun DYAH-meh-troh Rare

Origin: Greek diametros (line through the centre)

Usage Note

Diámetro carries a written accent on the first a to mark the antepenultimate stress, which differs from the English 'diameter' (stressed on the second syllable). It is masculine: el diámetro. The related adjective is diametral, and the adverb diametralmente (diametrically) appears in the idiom diametralmente opuesto (diametrically opposed), common in formal Spanish.

Examples

"El tubo tiene un diámetro de diez centímetros."

Natural Translation

The pipe has a diameter of ten centimetres.
