Articles married people may stand for (6)
I believe the answer is:
anthem
'people may stand for' is the definition.
I can't judge whether this defines the answer.
'articles married' is the wordplay.
'articles' becomes 'an the' (indefinite article 'an', definite article 'the').
'married' becomes 'm' (abbreviation, e.g. in genealogy).
'anthe'+'m'='ANTHEM'
Can you help me to learn more?
(Other definitions for anthem that I've seen before include "The man for a patriotic song" , "One for doomed youth" , "Song in praise of a nation" , "Religious chant" , "Song of praise or loyalty" .)
