Not consonant with promise made by the Spanish (5)
I believe the answer is:
vowel
'not consonant' is the definition.
'vowel' can be an answer for 'consonant' (thesaurus). I'm unsure of the 'not' bit.
'promise made by the spanish' is the wordplay.
'promise' becomes 'vow' (I've seen this in another clue).
'made by' says to put letters next to each other (letters written or made by another set of letters).
'the spanish' becomes 'el' ('the' in Spanish).
'vow'+'el'='VOWEL'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for vowel that I've seen before include "aeio or u" , "Letter such as i or u" , "Non-consonant" , "E.g. A, but not B" , "O for one" .)
