Elite forces given hard-to-get belt (4)
I believe the answer is:
sash
'belt' is the definition.
(sash is a type of belt)
'elite forces given hard-to' is the wordplay.
'elite forces' becomes 'SAS' (Special Air Service).
'given' says to put letters next to each other.
'hard-to' becomes 'h' (this could be a standard abbreviation which I don't know about).
'sas'+'h'='SASH'
'get' is the link.
Can you help me to learn more?
(Other definitions for sash that I've seen before include "Popular band in Northern Ireland" , "Girdle" , "Band - scarf" , "Cummerbund" , "Ribbon as a symbol of rank" .)
