Queued, having left to dine out (5)
I believe the answer is:
lined
'queued' is the definition.
Although both the answer and definition are past participle verbs, I don't understand how one could define the other.
'left to dine out' is the wordplay.
'left' becomes 'l' (common abbreviation).
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'dine' with letters rearranged gives 'ined'.
'l'+'ined'='LINED'
'having' is the link.
Can you help me to learn more?
(Other definitions for lined that I've seen before include "displaying signs of age" , "(Of a face) showing its age" , "Of face, marked with creases and wrinkles" , "Strengthened" , "with ruling" .)
