Big, strong guy with paper hanky’s last (5)
I believe the answer is:
hefty
'big' is the definition.
(I've seen this before)
'strong guy with paper hanky's last' is the wordplay.
'strong guy' becomes 'he' (I am not sure about this - if you are sure you should believe this answer much more).
'with' says to put letters next to each other.
'paper' becomes 'FT' (newspaper the FT, Financial Times).
'last' suggests the final letters.
The last letter of 'hanky' is 'y'.
'he'+'ft'+'y'='HEFTY'
Can you help me to learn more?
(Other definitions for hefty that I've seen before include "Muscular" , "Big and strong" , "Large and beefy" , "Sizeable" , "Brawny" .)
