Side with sage observing manner in which they're aren't allowed a word in? (8)
I believe the answer is:
edgewise
'manner in which they're aren't allowed a word in?' is the definition.
The definition suggests an adverb but the answer is an adverb.
'side with sage' is the wordplay.
'side' becomes 'edge' (edge is a kind of side).
'with' means one lot of letters go next to another.
'sage' becomes 'wise' (similar in meaning).
'edge'+'wise'='EDGEWISE'
'observing' is the link.
Can you help me to learn more?
(Other definitions for edgewise that I've seen before include "Sideways" , "Barely, as hardly getting a word in, say" .)
