Crewe also struggling, not given capital's treatment (5-4)

I believe the answer is:

lower case

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

'not given capital's treatment' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?

'crewe also struggling' is the wordplay.
'struggling' is an anagram indicator (the letters struggle or wriggle into a new form).
'crewe'+'also'='crewealso'
'crewealso' with letters rearranged gives 'LOWER-CASE'.

Can you help me to learn more?

(Other definitions for lower case that I've seen before include "small type" , "Not in capital letters" , "What a baggage-handler might do" , "Unlike sentence, initially" , "Minuscule" .)
