Mechanic on the right holds odd snips and indicates car part (7)
I believe the answer is:
chassis
'mechanic on the right' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'holds odd snips and indicates car part' is the wordplay.
'holds' becomes 'has' ('have' can be a synonym of 'hold').
'odd' means one should take alternating letters.
'and' says to put letters next to each other.
'indicates car part' becomes 'c' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
The alternate letters of 'snips' are 'sis'.
'has'+'sis'='hassis'
'hassis' put after 'c' is 'CHASSIS'.
Can you help me to learn more?
(Other definitions for chassis that I've seen before include "Vehicle structure" , "Car's structural framework" , "Vehicle base frame" , "it strengthens the body" , "vessel's structural framework" .)
