Give an account of man finally arriving having had a meal (7)
I believe the answer is:
narrate
'give an account' is the definition.
(I've seen this before)
'man finally arriving having had a meal' is the wordplay.
'finally' indicates one should take the final letters.
'arriving' becomes 'arr' (abbreviation used in transport).
'having' means one lot of letters go next to another.
'had a meal' becomes 'ate' (ate a meal).
The final letter of 'man' is 'n'.
'n'+'arr'+'ate'='NARRATE'
'of' acts as a link.
(Other definitions for narrate that I've seen before include "tell tales" , "Relate, recount" , "Relate events" , "'Recount, tell (7)'" , "Give a detailed account" .)
