Something memorable said on the way out? (6,4,5)
I believe the answer is:
famous last words
'something memorable said' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'the way out?' is the wordplay.
I cannot quite understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
'way' could be 'rd' (short for road) and 'rd' is found in the answer.
This explanation may well be incorrect...
'on' is the link.
Can you help me to learn more?
(Other definitions for famous last words that I've seen before include "Passing comment" , "Ill-judged comment" .)
