Bowled in wayward overs - bowled when in drink, as can be seen (10)
I believe the answer is:
observable
'in drink as can be seen' is the definition.
I can't tell whether this defines the answer.
'bowled in wayward overs bowled' is the wordplay.
'bowled' becomes 'b' (cricket abbreviation).
'in' means one lot of letters goes inside another.
'wayward' indicates anagramming the letters (wayward means out of control or chaotic).
'bowled' becomes 'able' (I can't justify this - if you can you should believe this answer much more).
'overs' with letters rearranged gives 'oserv'.
'b' put inside 'oserv' is 'observ'.
'observ'+'able'='OBSERVABLE'
'when' acts as a link.
Can you help me to learn more?
(Other definitions for observable that I've seen before include "on offer at peepshow?" , "Able to be seen" .)
