Sake? This can make you most unsteady! (8)

Ross

I believe the answer is:

shakiest

'most unsteady' is the definition.

'sake? this can make you' is the wordplay.
'can make you' indicates anagramming the letters.
'sake'+'this'='sakethis'
'sakethis' anagrammed gives 'SHAKIEST'.

(Other definitions for shakiest that I've seen before include "Least stable" , "most suspect" .)

I've seen this clue in The Times.
