Designed by Manet perhaps? (5)
I believe the answer is:
meant
'designed' is the definition.
(I've seen this before)
'manet perhaps?' is the wordplay.
'perhaps?' is an anagram indicator (I've seen 'perhaps' mean this).
'manet' anagrammed gives 'MEANT'.
'by' is the link.
(Other definitions for meant that I've seen before include "Deliberate" , "Had as intention or purpose" , "Had as purpose or design" , "proposed" , "Implied" .)
