Way anger about English is unproductive (7)
I believe the answer is:
sterile
'unproductive' is the definition.
(unable to reproduce)
'way anger about english' is the wordplay.
I cannot really see how this works, but
'way' could be 'st' (abbreviation for street) and 'st' is present in the answer.
'anger' could be 'rile' (rile can mean to annoy or anger) and 'rile' is present in the answer.
'english' could be 'e' (abbreviation) and 'e' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'is' is the link.
Can you help me to learn more?
(Other definitions for sterile that I've seen before include "Aseptic or infertile" , "unable to reproduce results" , "Antiseptic" , "Unable to have offspring" , "Not able to produce offspring" .)
