UK native heard the French can be sensitive (7)
I believe the answer is:
brittle
'sensitive' is the definition.
(thesaurus)
'uk native heard the french' is the wordplay.
'uk native' becomes 'brit' (I've seen this in another clue).
'heard' becomes 't' (I can't explain this - if you can you should believe this answer much more).
'the french' becomes 'le' ('the' in French).
'brit'+'t'+'le'='BRITTLE'
'can be' is the link.
Can you help me to learn more?
(Other definitions for brittle that I've seen before include "Fragile" , "Hard but easily broken" , "Type of toffee made with nuts" , "Easily cracked or snapped" , "Easy to break" .)
