Like paper sheet or most arguments (3-5)
I believe the answer is:
two-sided
'like' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for two-sided that I've seen before include "Double-faced" , "Having a pair of aspects" , "covering both opinions" .)
