French grammar - Asking questions using inversion

Asking questions in French can be straightforward - just use a normal declarative statement with a rising intonation at the end to make it a question.

But when the subject is a pronoun it is more common to form a question by inversion - that is by inverting the subject pronoun and verb and joining them with a hyphen.

With inversion question words like où ('where') and pourquoi ('why') should be moved to the beginning of the sentence.

Note that suis-je ('am I') is rarely used.

Note also that liaison is forbidden for inverted pairs. For example êtes-vous ici - there is NO liaison vou[z] even though the following word ici begins with a vowel.
