Soldiers look round for overhead protection (7)
I believe the answer is:
parasol
'overhead protection' is the definition.
'parasol' can be an answer for 'protection' (parasol is a kind of protection). I am unsure of the 'overhead' bit.
'soldiers look round' is the wordplay.
'soldiers' becomes 'paras' (para is a kind of soldier).
'look' becomes 'lo' ('lo' is an archaic exclamation meaning 'look!').
'round' shows that the letters should be reversed in order.
'lo' reversed gives 'ol'.
'paras'+'ol'='PARASOL'
'for' is the link.
Can you help me to learn more?
(Other definitions for parasol that I've seen before include ""Sunbrella"" , "Sunshade" , "protection from the rays" , "sunblock" , "Light umbrella to ward off the sun" .)
