Seconds in plenty with beef put in place (4)
I believe the answer is:
lieu
'place' is the definition.
(as in the phrase 'in lieu of')
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for lieu that I've seen before include "Stead - place" , "'In ..., instead (4)'" , "In ... of; in exchange for" , "In - of means instead of" , "Place - position" .)
