Engineers always included esteem (6)
I believe the answer is:
revere
'esteem' is the definition.
(I know that revere is a more specific form of the action esteem)
'engineers always included' is the wordplay.
'engineers' becomes 're' (abbreviation for Royal Engineers).
'always' becomes 'ever' (synonyms).
'included' is an insertion indicator.
're' going around 'ever' is 'REVERE'.
(Other definitions for revere that I've seen before include "Admire (someone) deeply" , "Hold in high respect" , "Honour greatly" , "Feel religious veneration for" , "Venerate - American hero" .)
