Bohemian learner joining a foreign religious house on holy island (14)
I believe the answer is:
unconventional
'bohemian' is the definition.
(similar in meaning)
'learner joining a foreign religious house on holy island' is the wordplay.
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'joining' means one lot of letters go next to another.
'a foreign' becomes 'un' ('a' translated into French).
'religious house' becomes 'convent' (I've seen this before).
'on holy island' becomes 'iona' (I can't explain this - if you can you should believe this answer much more).
'un'+'convent'+'iona'='unconventiona'
'l' put after 'unconventiona' is 'UNCONVENTIONAL'.
Can you help me to learn more?
(Other definitions for unconventional that I've seen before include "Free in one's ways" , "Nonconformist" , "Unorthodox" , "Not what you'd expect" .)
