Island like Man in Taiwan oddly (8)
I believe the answer is:
tasmania
'island' is the definition.
(Tasmania is an example)
'like man in taiwan oddly' is the wordplay.
'like' becomes 'as'.
'in' indicates putting letters inside.
'oddly' means one should take alternating letters (letters in the odd-numbered positions are used).
The alternating letters of 'taiwan' are 'tia'.
'as'+'man'='asman'
'asman' going within 'tia' is 'TASMANIA'.
(Other definitions for tasmania that I've seen before include "What a relief!" , "Australian island to south of Bass Strait" , "mountainous island" , "Island state off SE Australia, capital Hobart" , "Pacific island" .)
