Dressed up cellars, bringing in touch of hope - no longer this? (10)

I believe the answer is:

sepulchral

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

'no longer this?' is the definition.
The definition suggests a singular noun but the answer is not.

'dressed up cellars bringing in touch of hope' is the wordplay.
'dressed' is an anagram indicator ('dress' can mean 'prepare').
'bringing in' indicates putting letters inside.
'touch of' indicates taking the first letters.
The first letter of 'hope' is 'h'.
'up'+'cellars'='upcellars'
'upcellars' with letters rearranged gives 'sepulcral'.
'sepulcral' enclosing 'h' is 'SEPULCHRAL'.

Can you help me to learn more?

(Other definitions for sepulchral that I've seen before include "offering gloomy tones" , "from the grave" .)
