Gear placed over kind of business lot (6)
I believe the answer is:
kismet
'lot' is the definition.
(I've seen this in another clue)
'gear placed over kind of business' is the wordplay.
I cannot quite see how this works, but
'kind of business' could be 'sme' (short for small and medium-sized enterprises) and 'sme' is located in the answer.
'gear' could be 'kit' (kit is a kind of gear) and 'kit' is found in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for kismet that I've seen before include "fortune" , "Will of Allah" , "Fate - 1953 musical" , "Destiny; 50s musical" , "lot in life" .)
