Fish spear with no tip, maybe (9)
I believe the answer is:
perchance
'maybe' is the definition.
(synonyms)
'fish spear with' is the wordplay.
'fish' becomes 'perch' (perch is a kind of fish).
'spear with' becomes 'ance' (I am not sure about this - if you are sure you should believe this answer much more).
'perch'+'ance'='PERCHANCE'
'no tip' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for perchance that I've seen before include "possibly" , "As it may happen" , "Maybe (to dream? - Hamlet)" , "'To sleep: -------- to dream:' Hamlet" .)
