Question formation

Qui

• est-ce que va à la plage
• la plage
• elle aime la plage
• veut aller à la plage

Qui means 'who' and is followed by

• est-ce que
• inversion
• the il/elle FORM of the verb
• oui

step one to form a yes/no question is

• write the question
• make a statement with a subject and conjugated verb
• drop the ons off of the nous form
• add a question word

to form a yes/no question you can use

• qui
• est-ce 
• est-ce que or inversion
• inversion only

with inversion you must have 

• a person
• a subject
• a subject pronoun
• a verb ending in a vowel

when using inversion to form a yes/no question, you flip flop

• the subject pronoun and the conjugated verb
• the infinitive and the person
• drop the ons off of the nous form
• -T-

comment dit-on 'when'

• qui
• où
• quand
• comment

when using 'quel' you must have a 

• yes/no question
• a question word
• a noun
• -T-

There are 2 different ways to say 'what'

• quand and pourquoi
• qui et que
• quel et que
• comment et où

To form a complex question (how, when, where etc) after you have written your statement, you

• add the question word
• form a yes/no question and in front of that, add the question word
• repeat your statement
• make a yes/no question
