Learn French: Chante-t-il en anglais ? - Does he sing in English?

When you invert a verb that ends in a vowel (like chante) and a pronoun that starts with a vowel (like il, elle, or on), you have to add a -t- between them. This makes it easier to pronounce by preventing two vowel sounds from clashing.

Why are there hyphens connecting Chante, t, and il?

When you use subject-verb inversion to ask a question in French, you must connect the verb and the pronoun with a hyphen. Because we had to add the extra t here, it gets hyphens on both sides.

Do I always need to add a -t- when using inversion with il or elle?

No, you only do this when the verb ends in a vowel. If the verb already ends in a written consonant, like dit (says) or vend (sells), you do not add the -t-. For example, Dit-il ? (Does he say?) just takes one hyphen.

Why is it en anglais and not just anglais?
