Slightly drunk daughter left held by orderly (6)
I believe the answer is:
tiddly
'slightly drunk' is the definition.
(I've seen this before)
'daughter left held by orderly' is the wordplay.
'daughter' becomes 'd'.
'left' becomes 'l' (common abbreviation).
'held by' indicates putting letters inside.
'orderly' becomes 'tidy' ('tidy' can be similar in meaning to 'orderly').
'd'+'l'='dl'
'dl' put within 'tidy' is 'TIDDLY'.
(Other definitions for tiddly that I've seen before include "Merry" , "A little drunk" , "Slightly drunk or very small" , "Squiffy, pixilated" , "Tiny" .)
