Jittery racer gets around it in haphazard manner (7)
I believe the answer is:
erratic
'jittery racer gets around it in haphazard manner' is the definition.
I can't tell whether this defines the answer.
'jittery racer gets around it' is the wordplay.
'jittery' indicates anagramming the letters.
'gets' indicates putting letters inside (gets can mean captures or absorbs).
'around' is an anagram indicator.
'racer' anagrammed gives 'errac'.
'it' anagrammed gives 'ti'.
'errac' going around 'ti' is 'ERRATIC'.
Can you help me to learn more?
(Other definitions for erratic that I've seen before include "hit-and-miss" , "Irregular or uneven in movement or habit" , "Wild" , "Volatile" , "Uneven in movement or quality" .)
