Wisdom of epic yarn? It’s hardly a Hamlet (8)
I believe the answer is:
sagacity
'wisdom' is the definition.
(I know that sagacity is a type of wisdom)
'epic yarn? it's hardly a ihamleti' is the wordplay.
I cannot really understand how this works, but
'epic' could be 'saga' (I've seen this in another clue) and 'saga' is found within the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found within the answer.
This explanation may well be incorrect...
'of' is the link.
Can you help me to learn more?
(Other definitions for sagacity that I've seen before include "Astuteness" , "Good judgement, wisdom or shrewdness" , "of judgments" , "showing wisdom" , "It's a cagy kind of wisdom" .)
