Broadcast street name of drug, indicating rate at which it flies around? (8)
I believe the answer is:
airspeed
'drug indicating rate at which it flies around?' is the definition.
The definition suggests a singular noun which matches the answer.
'broadcast street name' is the wordplay.
'broadcast' becomes 'air' (to air on TV).
'street name' becomes 'speed' (I can't justify this - if you can you should believe this answer much more).
'air'+'speed'='AIRSPEED'
'of' is the link.
Can you help me to learn more?
(Other definitions for airspeed that I've seen before include "Flying velocity" , "Velocity of plane relative to the atmosphere" , "that keeps one flying?" , "rate of knots" , "Jumbo with such rapidity?" .)
