I get dizzy a lot with tinnitus, it's established (13)
I believe the answer is:
institutional
'established' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I can't see?
'i get dizzy a lot with tinnitus' is the wordplay.
'get' means one lot of letters goes inside another.
'dizzy' indicates an anagram.
'with' says to put letters next to each other.
'lot' after 'tinnitus' is 'tinnituslot'.
'a'+'tinnituslot'='atinnituslot'
'atinnituslot' with letters rearranged gives 'insttutional'.
'i' inserted inside 'insttutional' is 'INSTITUTIONAL'.
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for institutional that I've seen before include "from prison perhaps" , "Impersonal, unappealing" , "Like school" , "unappealingly impersonal" .)
