Ancho that's somewhat spicy (3)
I believe the answer is:
hot
'spicy' is the definition.
(synonyms)
'ancho that's somewhat' is the wordplay.
'somewhat' indicates the answer is hidden within the clue.
'HOT' is hidden within 'ancho that'.
(Other definitions for hot that I've seen before include "Flaming - spicy" , "Spicy or very warm" , "(Of food) spicy" , "Sultry or angry" , "SECOND PART OF 11" .)
