Take home earth and stone for grave (7)
I believe the answer is:
earnest
'grave' is the definition.
(thesaurus)
'take home earth and stone' is the wordplay.
'take home' becomes 'earn' (I've seen this before).
'earth' becomes 'e'.
'and' means one lot of letters go next to another.
'stone' becomes 'st'.
'earn'+'e'+'st'='EARNEST'
'for' acts as a link.
(Other definitions for earnest that I've seen before include "businesslike" , "Showing sincere and intense conviction" , "money involved in contract" , "Eastern (anag.)" , "Serious - down payment" .)
