Emphasise that a cricket club net is broken (6)
I believe the answer is:
accent
'emphasise' is the definition.
(synonyms)
'a cricket club net is broken' is the wordplay.
'a cricket club' becomes 'acc' (I can't explain this - if you can you should give a lot more credence to this answer).
'is broken' indicates anagramming the letters.
'net' anagrammed gives 'ent'.
'acc'+'ent'='ACCENT'
'that' is the link.
Can you help me to learn more?
(Other definitions for accent that I've seen before include "Underline" , "Mark used to indecate pronunciation" , "Emphasis; mark on a letter" , "A diacritic mark" , "It could be acute" .)
