Tell engineers to get quote (6)
I believe the answer is:
recite
'tell' is the definition.
(I know that tell can be written as recite)
'engineers to get quote' is the wordplay.
'engineers' becomes 're' (Royal Engineers).
'to get' means one lot of letters go next to another.
'quote' becomes 'cite' (synonyms).
're'+'cite'='RECITE'
(Other definitions for recite that I've seen before include "Repeat aloud from memory, say poetry" , "Render verbally" , "Intone" , "Declaim aloud" , "Speak by heart aloud" .)
