Shingle formation academically studied (7)
I believe the answer is:
english
'academically studied' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives sometimes mean the same thing.
'shingle formation' is the wordplay.
'formation' is an anagram indicator.
'shingle' is an anagram of 'ENGLISH'.
Can you help me to learn more?
(Other definitions for english that I've seen before include "An official language of the Republic of India" , "Tongue" , "This nationality found in shingle" , "Common language" , "The . . . . . . . Patient (film) (7)" .)
