Put money in, having lost one's shirt? (6)
I believe the answer is:
invest
'put money' is the definition.
(I've seen this before)
'in having lost one's shirt?' is the wordplay.
'having' says to put letters next to each other.
'lost one's shirt?' becomes 'vest' (I am not sure about this - if you are sure you should believe this answer much more).
'in'+'vest'='INVEST'
Can you help me to learn more?
(Other definitions for invest that I've seen before include "speculate?" , "Eg, buy stocks and shares" , "Put money into in hopes of a return" , "Put money into shares, property, etc" , "Put money into business for profit" .)
