Type of accountant, for example, invested in island (8)
I believe the answer is:
category
'type' is the definition.
(I've seen this before)
'accountant for example invested in island' is the wordplay.
'accountant' becomes 'ca' (abbreviation for chartered accountant).
'for example' becomes 'eg' ('e.g.' can be a synonym of 'for example').
'invested in' indicates putting letters inside.
'island' becomes 'tory' (I can't explain this - if you can you should give a lot more credence to this answer).
'eg' placed inside 'tory' is 'tegory'.
'ca'+'tegory'='CATEGORY'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for category that I've seen before include "Classification of grey-coat" , "Kind" , "Class of grey coat" , "Logical grouping" , "Coy Greta found among this class of things" .)
