Gun I have to pack for the trip (6)
I believe the answer is:
outing
'trip' is the definition.
(I've seen this before)
'gun i have to pack for the' is the wordplay.
I cannot really understand how this works, but
'i' is present in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
an anagram of 'gun' is 'ung' which is present in the left over letters.
A single letter 'o' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for outing that I've seen before include "Day excursion" , "Short pleasure trip" , "Jaunt" , "A trip in the open air" , "Excursion, trip" .)
