EHĒCA pret: EHĒCAC to blow lightly, for there to be a breeze, to be windy / hacer viento, o aire (M) An unreduplicted verb stem related to this is to be expected, but none is attested. This verb and the related noun have identical stems. R has a short vowel and glottal stop in the second syllable in place of a long vowel EHEHCA. See EHĒCA-TL.
