Matching set of furniture in clubs perhaps, ultimately adequate (5)
I believe the answer is:
suite
'matching set of furniture' is the definition.
'suite' can be an answer for 'furniture' (I have seen 'The furniture' mean 'suite' so perhaps 'furniture' could also mean 'suite'). I'm unsure of the 'matching set of' bit.
'clubs perhaps ultimately adequate' is the wordplay.
'clubs perhaps' becomes 'suit' (clubs is a playing card suit).
'ultimately' suggests the final letters.
The final letter of 'adequate' is 'e'.
'suit'+'e'='SUITE'
'in' is the link.
Can you help me to learn more?
(Other definitions for suite that I've seen before include "Collection of pieces" , "Compensate for (faults)" , "Retinue; apartment" , "Extensive accommodation" , "Train; set of rooms" .)
