What does "kiki" mean?  I understand it in context, but wonder if it has a life of its own.  Thanks.

Are there parts of France where they use the verb savoir to mean pouvoir?  I am told this is a tendency of speakers in Belgium.

Thought espérer does not take subjuntive.

What is the rule governing whether or not the reflexive construction is used?  It seems clear with personal verbs like brushing ones teeth or cutting one’s hair, but not clear at all in the context of having sandals made. 

Are both of these sentences grammatically correct? I understand why 'ce qui' in the first sentence is correct, but not why 'ce que' would be correct in the second one. I would be grateful for an explanation.

Ce qui à un moment donné est le substrat, n’est pas chaud

The passive voice in several examples where we needed "was sent" and "had prepared" used plus que parfait ie) était envoyé and avait préparé, but for "the students were welcomed", my use of étaient accueillis was incorrect and the correct answer was the p.c.: Les étudiants ont été accueillis was correct. This seems illogical to me. Please explain the difference.
