Give to understand that the top comes off easily (5)
I believe the answer is:
imply
'give' is the definition.
(I know this)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for imply that I've seen before include "State indirectly" , "Indicate indirectly" , "Mean" , "Infer" , "Intimate, suggest indirectly" .)
