Thanks for top cheese with very fine silky material (7)
I believe the answer is:
taffeta
'very fine silky material' is the definition.
'taffeta' can be an answer for 'material' (taffeta is a kind of material). I'm not certain of the 'very fine silky' bit.
'thanks for top cheese' is the wordplay.
'thanks' becomes 'ta' (UK informal version of 'thank you').
'top' indicates taking the first letters (in a down clue, the first letter is top).
'cheese' becomes 'feta' (type of cheese).
The first letter of 'for' is 'f'.
'ta'+'f'+'feta'='TAFFETA'
'with' is the link.
Can you help me to learn more?
(Other definitions for taffeta that I've seen before include "Thin glossy silk fabric" , "Thin crisp lustrous silk" , "Lustrous silky fabric" , "Fine crisp lustrous fabric" , "Thin silky material" .)
