Nurse in Lima adjusted routine (6)
I believe the answer is:
menial
'routine' is the definition.
(thesaurus)
'nurse in lima adjusted' is the wordplay.
'nurse' becomes 'en' (abbreviation for enrolled nurse).
'in' indicates putting letters inside.
'adjusted' indicates anagramming the letters.
'lima' anagrammed gives 'mial'.
'en' going into 'mial' is 'MENIAL'.
(Other definitions for menial that I've seen before include "Servile, low" , "Inferior like servant" , "(Of job) low in prestige" , "Demeaning" , "'Humble, lowly, work say (6)'" .)
