Order a stove, installing cooker at the back (7)
I believe the answer is:
arrange
'order' is the definition.
(I know that order is a more specific form of the action arrange)
'a stove installing cooker at the back' is the wordplay.
'stove' becomes 'range' (synonyms).
'installing' means one lot of letters goes inside another (inserted letters are installed).
'at the back' says to take the final letters (the letter at the back).
The last letter of 'cooker' is 'r'.
'range' going around 'r' is 'rrange'.
'a'+'rrange'='ARRANGE'
(Other definitions for arrange that I've seen before include "Marshal" , "Bring about or put in order" , "Put in order; make plans" , "Plan, organize" , "Fix" .)
