Court in support over proposed US constitutional amendment and the like (2,6)
I believe the answer is:
et cetera
'and the like' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for et cetera that I've seen before include "That can reduce length of sentence" , "And similar things" , "and the others" , "something similar" , "And the rest (Latin)" .)
