Company vehicle - one seen next to loch (8)
I believe the answer is:
business
'company' is the definition.
(I've seen this before)
'vehicle one seen next to loch' is the wordplay.
'vehicle' becomes 'busi' (I am not sure about this - if you are sure you should believe this answer much more).
'one seen next to' means one lot of letters go next to another.
'loch' becomes 'ness' (Loch Ness in Scotland).
'busi'+'ness'='BUSINESS'
Can you help me to learn more?
(Other definitions for business that I've seen before include "Commercial or industrial enterprise" , "Baby" , "Work - shop" , "Commerce, trace" , "Occupation; trade" .)
