Washed tights beginning to dry? (5)
I believe the answer is:
hosed
'washed' is the definition.
(I've seen this before)
'tights beginning to dry?' is the wordplay.
'tights' becomes 'hose' (synonyms).
'beginning to' suggests taking the first letters.
The first letter of 'dry' is 'd'.
'hose'+'d'='HOSED'
(Other definitions for hosed that I've seen before include "Watered with a flexible pipe" , "swilled down with water" , "wearing tights?" , "washed" .)
