Vortex that inspired Dyson hoovers? (4)
I believe the answer is:
eddy
'vortex' is the definition.
(I've seen this in another clue)
'inspired dyson hoovers?' is the wordplay.
'EDDY' is hidden in amongst the letters.
However, I am not sure how the hidden word is indicated.
'that' acts as a link.
Can you help me to learn more?
(Other definitions for eddy that I've seen before include "Circular movement of air" , "Ripple" , "(Of fluid) circle round" , "Twist" , "Swirl, whirl" .)
