Get on top of Daisy, married earlier (6)
I believe the answer is:
master
'get' is the definition.
(thesaurus)
'on top of daisy married earlier' is the wordplay.
'on top of' says to put letters next to each other.
'daisy' becomes 'aster' (I've seen this before).
'married earlier' becomes 'm' (abbreviation, e.g. in genealogy. I am not sure about the 'earlier' bit.).
'aster' put after 'm' is 'MASTER'.
Can you help me to learn more?
(Other definitions for master that I've seen before include "'Jack of all trades and . . . . . . of none'" , "Main; overcome; original recording" , "Male teacher or ship's captain" , "Teacher to gain control" , "One has consummate skill" .)
