Engineers certain to go after a record again (9)
I believe the answer is:
remeasure
'engineers certain to go after a record again' is the definition.
I can't tell whether this defines the answer.
'engineers certain to go after a' is the wordplay.
'engineers' becomes 'reme' (Royal Electrical and Mechanical Engineers).
'certain' becomes 'sure' (synonyms).
'to go after' says to put letters next to each other.
'sure' put after 'a' is 'asure'.
'reme'+'asure'='REMEASURE'
Can you help me to learn more?
(Other definitions for remeasure that I've seen before include "rank again" , "Again ascertain length" .)
