Mini cyclone's vibratory sound and large twist (9)
I believe the answer is:
whirlwind
'mini cyclone's' is the definition.
'whirlwind' can be an answer for 'cyclone's' (I've seen this before). I am not certain of the 'mini' bit.
'vibratory sound and large twist' is the wordplay.
'vibratory sound' becomes 'whir' (I've seen this in another clue).
'and' is a charade indicator (letters next to each other).
'large' becomes 'L' (eg in clothes sizes).
'twist' becomes 'wind' (synonyms).
'whir'+'l'+'wind'='WHIRLWIND'
Can you help me to learn more?
(Other definitions for whirlwind that I've seen before include "Mass of air in violent spiral motion" , "(Of a romance) rapidly sweeping you off your feet?" , "Impulsive" , "E.g. a dust devil" , "Energetic person" .)
