Poor Lear, interrupted by one from another play (5)
I believe the answer is:
ariel
'another play' is the definition.
The definition suggests a singular noun which matches the answer.
'poor lear interrupted by one' is the wordplay.
'poor' indicates an anagram.
'interrupted by' means one lot of letters goes inside another.
'one' becomes 'i' (Roman numeral).
'lear' anagrammed gives 'arel'.
'arel' placed around 'i' is 'ARIEL'.
'from' is the link.
Can you help me to learn more?
(Other definitions for ariel that I've seen before include "Arabian mountain gazelle" , "Prospero's spirit (Tempest)" , "Character pined once, unable to escape" , "fairy sign" , "Shakespearian sprite - Uranus satellite - gazelle" .)
