Meets a club host over in front of system (7)
I believe the answer is:
adjoins
'meets' is the definition.
(adjoining is a kind of meeting)
'a club host over in front of system' is the wordplay.
'club host' becomes 'dj' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'over' means one lot of letters goes inside another.
'front' indicates taking the first letters.
The initial letters of 'of system' is 'os'.
'in' placed inside 'os' is 'oins'.
'a'+'dj'+'oins'='ADJOINS'
Can you help me to learn more?
(Another definition for adjoins that I've seen is " Lies adjacent to".)
