This is a line from an old song--> "Qu'il y'en a un sur deux qui n'est jamais heureux."

What does en do/mean here? 

to help me remember which demonstrative pronoun to use.  I'm surprised i haven't come across this somewhere else because now it seems obvious to me.

Anyway, thought i'd share in case it can help others.

Think of them like this:

ce-lui

c-eux

c-elle

c-elles

of course, just remove the hyphen and you have your correct demonstrative pronoun!

Ex. from above:  Ils ont réussi à la convaincre.  Subject They/verb succeeded - requires preposition à before infinitive verb convaincre to convince?

  I am wondering why "la" direct object is used here instead of "lui" please?  Merci!
