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

'most common' is the definition.
'prevailing' can be an answer for 'common' (thesaurus). I am not sure about the 'most' bit.

'page's revised poorly' is the wordplay.
'page' becomes 'p'.
'revised' becomes 'rev' (I can't justify this - if you can you should give a lot more credence to this answer).
'poorly' becomes 'ailing' (synonyms).
'p'+'rev'+'ailing'='PREVAILING'

Can you help me to learn more?

(Other definitions for prevailing that I've seen before include "Generally accepted" , "ruling" , "victorious" .)
