Here are some examples:**
Bancos têm de fazer com que o cliente distinga produtos com e sem risco
Faremos com que o caminho da violência para a política seja mais difícil de percorrer.
Chegou a hora de virar a página e de fazer com que a projecto europeu encarrilhe de novo.
It seems that the word means to make or to cause something to happen ("make the client distinguish", "make the path harder" and "make the project restart", respectively). Is that roughly correct and a good guide to when this verb should be used?
I'm also curious if this way of speaking has some ties to formality/informality or regional dialects. Some corners of the internet have reported that fazer com que is ungrammatical; if that's true, does it influence where it is appropriate to use it?
