Commercial vehicle going over Scotland emptied site in Faslane say (5,4)
I believe the answer is:
naval base
'faslane say' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'commercial vehicle going over scotland emptied site' is the wordplay.
'commercial vehicle' becomes 'van' (I've seen this before).
'going over' says the letters should be written backwards.
'scotland' becomes 'Alba' (Gaelic name for Scotland).
'emptied' means to remove the middle letters.
'site' with its middle taken out is 'se'.
'van' back-to-front is 'nav'.
'nav'+'alba'+'se'='NAVAL BASE'
'in' acts as a link.
Can you help me to learn more?
(Another definition for naval base that I've seen is " For example, Norfolk, Va or Portsmouth, Hants".)
