Pressure to take drugs over heart complaint? Presumably, Garda is looking into that! (5)
I believe the answer is:
pulse
'pressure to take drugs over heart complaint? presumably garda is looking into that' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'pressure to take drugs over heart complaint?' is the wordplay.
'pressure' becomes 'p' (abbreviation).
'to take drugs' becomes 'use' (use can mean to take drugs).
'over' is an insertion indicator.
'heart' indicates the central letters.
The middle letter of 'complaint' is 'l'.
'use' going around 'l' is 'ulse'.
'p'+'ulse'='PULSE'
Can you help me to learn more?
(Other definitions for pulse that I've seen before include "Rhythmic throbbing" , "Bustle" , "Rhythmical throb of arteries" , "often sought medically?" , "Lentil, bean, seeds" .)
