Provided money for marriage of Steven and Di? (8)
I believe the answer is:
invested
'provided' is the definition.
(thesaurus)
'of steven and di?' is the wordplay.
'of' indicates anagramming the letters (the answer comes from or 'of' the letters).
'and' says to put letters next to each other.
'steven' after 'di' is 'disteven'.
'disteven' is an anagram of 'INVESTED'.
'money for marriage' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for invested that I've seen before include "Put money in shares, etc" , "Put money into in expectation of profit" , "Bought shares" .)
