Country beat interrupted by precipitation gets finished finally (8)
I believe the answer is:
thailand
'country' is the definition.
(Thailand is an example)
'beat interrupted by precipitation gets finished finally' is the wordplay.
'beat' becomes 'tan' (I've seen this before**).
'interrupted by' is an insertion indicator.
'precipitation' becomes 'hail' (hail is a kind of precipitation).
'gets' says to put letters next to each other.
'finally' says to take the final letters.
The last letter of 'finished' is 'd'.
'tan' enclosing 'hail' is 'thailan'.
'thailan'+'d'='THAILAND'
(Other definitions for thailand that I've seen before include "Formerly Siam" , "SE Asian country" , "Phuket's location" , "Country in SE Asia, capital of Bangkok" , "Southeast Asian country" .)
