Names are strange, seem nocturnal (13)
I believe the answer is:
nomenclatures
'names' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Perhaps you can see an association between them that I can't see?
'strange seem nocturnal' is the wordplay.
'strange' indicates an anagram.
'seem'+'nocturnal'='seemnocturnal'
'seemnocturnal' with letters rearranged gives 'NOMENCLATURES'.
'are' is the link.
Can you help me to learn more?
I've seen this clue in The Hindu.
Want a hint initially instead of a full solution?
