Returns and is at home before you arrive (6)
I believe the answer is:
income
'returns' is the definition.
(I've seen this before)
'is at home before you arrive' is the wordplay.
I cannot quite see how this works, but
'at' could be 'in' (synonymous in some cases - eg at school, in school) and 'in' is located in the answer.
'arrive' could be 'come' (synonyms) and 'come' is found within the answer.
No letters remain.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for income that I've seen before include "Money earned" , "Money gained from work or investment" , "Money received on which tax is payable" , "Money from investments or for work" , "Financial gain accruing over a given period of time" .)
