Overinterpret peer leaving unexpectedly - she just needs more quiet time (9)
I believe the answer is:
introvert
'she just needs more quiet time' is the definition.
I can't tell whether this definition defines the answer.
'overinterpret peer leaving unexpectedly' is the wordplay.
'leaving' suggests deleting specific letters.
'unexpectedly' is an anagram indicator.
'overinterpret' with 'peer' taken away is 'ovintrret'.
'ovintrret' with letters rearranged gives 'INTROVERT'.
Can you help me to learn more?
(Other definitions for introvert that I've seen before include "Shy type" , "Shy and reticent person" , "Self-absorbed person" , "eschewing external contact" , "One who's withdrawn" .)
