Random: this is more, though not entirely, haphazard (3-2-4)
I believe the answer is:
hit-or-miss
This could be a double definition.
'random' is the first definition.
(hit or miss can mean unpredictable or inconsistent)
'more though not entirely haphazard' is the second definition.
'hit or miss' can be an answer for 'haphazard' (I've seen this before). I am not certain of the 'more though not entirely' bit.
'this is' acts as a link.
Can you help me to learn more?
(Other definitions for hit-or-miss that I've seen before include "Of method, erratic or random" , "Haphazard, random" .)
