Managed to do a lot in a haphazard way (6)
I believe the answer is:
random
'in a haphazard way' is the definition.
I can't judge whether this definition defines the answer.
'managed to do a lot' is the wordplay.
'managed' becomes 'ran' (both can mean organised or was in charge of).
'to' says to put letters next to each other.
'a lot' becomes 'm' ().
'ran'+'do'+'m'='RANDOM'
Can you help me to learn more?
(Other definitions for random that I've seen before include "Disorganised" , "Roderick came before it" , "Patternless" , "Hit-or-miss" , "Happening by chance, haphazard" .)
