Surrounded by some pyramids (4)

I believe the answer is:

amid

'surrounded by' is the definition.
(I've seen this before)

'some pyramids' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'AMID' is hidden within 'pyramids'.

(Other definitions for amid that I've seen before include "In the thick of" , "In the middle of" , "In the centre of" , "Amongst" , "'See . . . . the winter's snow' (carol)" .)

I've seen this clue in the Evening Standard.
