Very loudly exercise in wood when it’s supposed to be quiet (3-4)
I believe the answer is:
off-peak
'it's supposed to be quiet' is the definition.
I can't tell whether this defines the answer.
'very loudly exercise in wood' is the wordplay.
'very loudly' becomes 'ff' (short for fortissimo, 'very loud' in music).
'exercise' becomes 'pe' (Physical Education).
'in' means one lot of letters goes inside another.
'wood' becomes 'oak' (oak is a kind of wood).
'ff'+'pe'='ffpe'
'ffpe' going into 'oak' is 'OFF-PEAK'.
'when' is the link.
Can you help me to learn more?
(Other definitions for off-peak that I've seen before include "Fake fop (anag.)" , "Time when tickets are usually cheaper" , "Less busy (time)" , "At a time when demand is less" , "Not at the time of highest demand" .)
