Poet's article getting around hurdles at regular points (5)
I believe the answer is:
auden
'poet's' is the definition.
(WH Auden, 1907-1973)
'article getting around hurdles at regular points' is the wordplay.
'article' becomes 'an' (indefinite article).
'getting around' means one lot of letters goes inside another.
'at regular points' means one should take alternating letters.
The alternate letters of 'hurdles' are 'ude'.
'an' going around 'ude' is 'AUDEN'.
(Other definitions for auden that I've seen before include "W. H. -, English poet" , "W. H. -, Eng. poet" , "W. H. -, English-born poet" , "British-born American poet" , "British-born writer" .)
