Shower one new pet with designer clothing (9)
I believe the answer is:
indicator
'shower' is the definition.
(I've seen this before)
'one new pet with designer clothing' is the wordplay.
I cannot really understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found in the answer.
'new' could be 'n' (common abbreviation eg NT for New Testament) and 'n' is located in the answer.
'pet' could be 'cat' (cats are often kept as pets) and 'cat' is present in the answer.
'designer' could be 'dior' (dior is a designer brand) and 'dior' is found in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for indicator that I've seen before include "Gauge, meter" , "Pointer" , "Gauge; information board" , "Station information board" , "Car's flashing light" .)
