Join me as ordered (4)
I believe the answer is:
seam
'join' is the definition.
(I know that seam is a kind of join)
'me as ordered' is the wordplay.
'ordered' indicates an anagram.
'me'+'as'='meas'
'meas' is an anagram of 'SEAM'.
(Other definitions for seam that I've seen before include "Stratum (of a mineral)" , "Fabric joint" , "A layer of coal in ground" , "Stratum of ore or coal" , "Join - stratum of ore" .)
