Odd odes and singular measures (5)
I believe the answer is:
doses
'measures' is the definition.
(dose is a kind of measure)
'odd odes and singular' is the wordplay.
'odd' is an anagram indicator.
'and' means one lot of letters go next to another.
'singular' becomes 's' (abbreviation sometimes used in dictionaries).
'odes' with letters rearranged gives 'dose'.
'dose'+'s'='DOSES'
(Other definitions for doses that I've seen before include "Specific quantities" , "Prescribed quantities of medicine" , "Prescribed amounts of medication" , "Quanitites of medicine" , "Prescribed amounts of medicine" .)
