A blow that has to be faced (8)
I believe the answer is:
headwind
'a blow that has to be faced' is the definition.
The definition and answer can be both types of natural phenomena as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'a blow that has to be' is the wordplay.
'a blow' becomes 'wind'.
'that has' says to put letters next to each other.
'to be' becomes 'head' (heading is a kind of being).
'wind' after 'head' is 'HEADWIND'.
Can you help me to learn more?
(Other definitions for headwind that I've seen before include "It blows straight into your face" , "Stiff breeze blowing directly in front" , "Contrary breeze" , "opposing force" , "Current of air blowing into the bow of ship" .)
