Shrill cries from goal upset our wimpish striker initially (6)
I believe the answer is:
miaows
'shrill cries' is the definition.
'miaows' can be an answer for 'cries' (miaow is a kind of cry). I am not certain of the 'shrill' bit.
'goal upset our wimpish striker initially' is the wordplay.
'goal' becomes 'aim' (aim is a kind of goal).
'upset' shows that the letters should be reversed in order.
'initially' suggests taking the first letters.
The first letters of 'our wimpish striker' is 'ows'.
'aim' back-to-front is 'mia'.
'mia'+'ows'='MIAOWS'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for miaows that I've seen before include "Catcalls" , "Makes a catty noise" , "Sounds like a cat" .)
