Does order correct number of pills (4)
I believe the answer is:
dose
'number of pills' is the definition.
'dose' can be an answer for 'number' (thesaurus). I'm not certain of the 'of pills' bit.
'does order correct' is the wordplay.
'does' anagrams to 'DOSE'.
But, I'm not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for dose that I've seen before include "some Viagra, perhaps?" , "Measure of medicine" , "Measure of drug" , "Measured quantity of medicine" , "Measured portion of medicine" .)
