A vehicle one picked up to get through quiet grassy area (8)
I believe the answer is:
savannah
'grassy area' is the definition.
'savannah' can be an answer for 'area' (savannah is a kind of area). I am not sure about the 'grassy' bit.
'a vehicle one picked up to get through quiet' is the wordplay.
'vehicle' becomes 'van' (type of vehicle).
'one' becomes 'an' (an apple is one apple).
'picked up' says the letters should be written in reverse.
'to get through' is an insertion indicator.
'quiet' becomes 'sh' (both can be said to tell someone to be quiet).
'an' reversed gives 'na'.
'a'+'van'+'na'='avanna'
'avanna' inserted into 'sh' is 'SAVANNAH'.
Can you help me to learn more?
(Other definitions for savannah that I've seen before include "A grassy plain in hot regions with no trees" , "plain [to see]" , "somewhere in Georgia" , "Flat grassland in hot regions" , "US port" .)
