Fugitive has last piece of treasure taken in robbery (5,2)
I believe the answer is:
holed up
'fugitive' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives can occasionally mean the same thing.
'last piece of treasure taken in robbery' is the wordplay.
'last piece of' indicates one should take the final letters.
'taken in' indicates putting letters inside.
'robbery' becomes 'holdup' (holdup is a kind of robbery).
The final letter of 'treasure' is 'e'.
'e' inserted into 'holdup' is 'HOLED UP'.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for holed up that I've seen before include "went into hiding" , "hidden'" .)
