How to Say Cactus in Spanish: Cactus, Cacto & Nopal
Cactus · noun (masculine) · KAHK-toos
Cactus is cactus in Spanish — same spelling, different pronunciation (KAHK-toos). It is masculine (el cactus) and does not change in the plural (los cactus). The form cacto is accepted by the RAE but rare in conversation. In Mexico, nopal refers specifically to the prickly pear cactus (Opuntia), which is eaten as a vegetable and appears on the Mexican flag.
Cactus is KAHK-toos, two syllables. The u is pronounced (oo), unlike some English speakers who reduce it. Nopal is noh-PAHL, stress on the last syllable.
