Oddly, I am not quite so haphazard (7)
I believe the answer is:
aimless
'quite so haphazard' is the definition.
'aimless' can be an answer for 'haphazard' (thesaurus). I'm unsure of the 'quite so' bit.
'oddly i am not' is the wordplay.
'oddly' indicates an anagram.
'not' becomes 'less' (I've seen this in other clues**).
'i'+'am'='iam'
'iam' with letters rearranged gives 'aim'.
'aim'+'less'='AIMLESS'
Can you help me to learn more?
(Other definitions for aimless that I've seen before include "Without objectives" , "lacking direction" , "without sense of purpose" , "Without purpose or direction" , "With no plan or programme" .)
