Parent into Jack Kerouac at last — it's On The Road (6)
I believe the answer is:
tarmac
'road' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'parent into jack kerouac at last it's on' is the wordplay.
'parent' becomes 'ma' (ma can mean mum or mother).
'into' is an insertion indicator.
'jack' becomes 'tar' (both are informal terms for sailor).
'at last' indicates one should take the final letters.
'it's on' says to put letters next to each other.
The last letter of 'kerouac' is 'c'.
'tar'+'c'='tarc'
'ma' placed within 'tarc' is 'TARMAC'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for tarmac that I've seen before include "Road paving material" , "Road surface material of tar and stone" , "Surface material of tar and broken stone" , "Surfaced area for plane to land" , "something for the road" .)
