(He likes this film. => Does he like this film?)
Inversion
This is considered to be the most formal way to ask a question out of the three.
(The indicative form of the following sentences will be placed in parentheses for comparison.)
To ask a question by inversion, simple invert the verb and the subject (the pronoun) and insert a hyphen (un
trait d'union) in between.
Example: Do you like apples? (You like apples.)
Aimes-tu les pommes ? (Tu aimes les pommes.)
In the case where the verb ends in a vowel while the subject starts with one, a "t" needs to be inserted to
avoid elision.
Example: Did she make the decision already? (She made the decision already.)
A-t-elle déjà pris la décision ? (Elle a déjà pris la décision.)
(Notice that for compound tense [les temps composés], only the avoir or être part is interchanged with the
subject.)
For third person plural (verbs ending in "ent"), there is no need to insert the "t".
Example: Are they buying a house? (They are buying a house.)
Achètent-ils une maison ? (Ils achètent une maison.)
If the subject is a noun instead of a pronoun, invert the verb and the pronoun that represents the subject.
Example: Did Marie choose this shirt? (Marie chose this shirt.)
'Marie a-t-elle choisi cette chemise ? (Marie a choisi cette chemise.)
For negative such as "ne...pas", the verb should be inserted in between:
Example: Didn't you eat the whole pizza? (You didn't eat the whole pizza.)
N'as-tu pas mangé la pizza entière ? (Tu n'as pas mangé la pizza entière.)
If there is a direct or indirect object (complément d'objet [in]direct), it goes before the verb.
Example: Have you been there? (You have been there.)
Y es-tu allé(e) ? (Tu y es allé(e).)
