ocotillo

the word 'ocotillo' entered english in the mid-19th century from mexican spanish. its origin traces back to the nahuatl word 'ocotl', which referred to the pine tree or, by extension, a torch made from its resinous wood. the spanish adapted this term, adding the diminutive suffix '-illo', likely to describe a plant that was smaller or resembled the pine in some way—perhaps in its use as a torch-like implement or the appearance of its flowering stalks. the english adoption retains the original spanish spelling and pronunciation, applying it specifically to the distinctive desert shrub whose tall, fiery red flower clusters may have evoked the image of a small torch.

this word is a direct loanword from mexican spanish, where it is a diminutive form of the nahuatl word 'ocotl', meaning 'pine tree' or 'torch'. the spanish suffix '-illo' adds a diminutive or descriptive sense.
