Regularly talk big about journalists’ entertainment on the slopes (5-3)
I believe the answer is:
apres-ski
'entertainment on the slopes' is the definition.
'apres ski' can be an answer for 'entertainment' (I've seen this before). I am not sure about the 'on the slopes' bit.
'regularly talk big about journalists'' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'about' indicates putting letters inside.
'journalists'' becomes 'press' (the press can mean the newspaper industry).
'talk'+'big'='talkbig'
The alternate letters of 'talkbig' are 'aki'.
'aki' enclosing 'press' is 'APRES-SKI'.
Can you help me to learn more?
(Other definitions for apres-ski that I've seen before include "Alpine holiday fun?" , "Party following winter sports" , "Social activity following session on the piste" , "holiday entertainment" , "Alpine jollities" .)
