'primarily christmas air noel regularly featured?' is the definition.
I can't judge whether this definition defines the answer.

'primarily christmas air noel regularly' is the wordplay.
'primarily' indicates taking the first letters.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
The first letter of 'christmas' is 'c'.
'air'+'noel'='airnoel'
The alternate letters of 'airnoel' are 'arol'.
'c'+'arol'='CAROL'

Can you help me to learn more?
