I believe the answer is:

present tense

I'm a little stuck... Click here to teach me more about this clue!

'part of speech' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe there's a link between them I don't understand?

'spenser tenet reworked' is the wordplay.
'reworked' indicates an anagram.
'spenser'+'tenet'='spensertenet'
'spensertenet' with letters rearranged gives 'PRESENT TENSE'.

'into' is the link.

Can you help me to learn more?
