Unites English in trouble (5)
I believe the answer is:
fuses
'unites' is the definition.
The definition and answer can be both related to change as well as being verbs in their -s form.
Maybe you can see an association between them that I can't see?
'english in trouble' is the wordplay.
I cannot quite see how this works, but
'english' could be 'e' (abbreviation) and 'e' is present in the answer.
'trouble' could be 'fuss' (synonyms) and 'fuss' is found within the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for fuses that I've seen before include "Blow one of these and lose your temper" , "Blends or amalgamates, say metals" , "They interrupt the electric current when they're overloaded" , "Electrical safety devices" , "bonds" .)
