Are told to accommodate the girl (7)
I believe the answer is:
heather
'girl' is the definition.
'are told to accommodate the' is the wordplay.
'are told' becomes 'hear' (I can't justify this - if you can you should give a lot more credence to this answer).
'to accommodate' means one lot of letters goes inside another.
'hear' going around 'the' is 'HEATHER'.
Can you help me to learn more?
(Other definitions for heather that I've seen before include "Another term for ling" , "Girl's name - ling" , "Calluna vulgaris" , "Ericaceous shrub" , "Erica!" .)
