The end is nigh (5)

I believe the answer is:

I believe this clue is a double definition.

'the end' is the first definition.
(close can mean the closing part of something)

'is nigh' is the second definition.
(similar in meaning)

(Other definitions for close that I've seen before include "Not far off" , "nigh" , "cul-de-sac" , "Near - shut" , "Near; bring to an end" .)

I've seen this clue in The Globe and Mail and The Independent.
