Article in news strangely peters out (5)
I believe the answer is:
wanes
'article in news strangely peters out' is the definition.
I can't judge whether this defines the answer.
'article in news strangely' is the wordplay.
'article' becomes 'a' (indefinite article).
'in' means one lot of letters goes inside another.
'strangely' indicates an anagram.
'news' with letters rearranged gives 'wnes'.
'a' put inside 'wnes' is 'WANES'.
Can you help me to learn more?
(Other definitions for wanes that I've seen before include "Grows smaller like the moon" , "Decreases in vigour or strength like the moon" , "Gradually declines" , "Of the moon, gradually decreases" .)
