Ask about plans: inversion questions with question words

The French [g] has two sounds: soft before the letters e, i and y and hard before other letters. We use 'aller' in the present tense followed by an infinitive to talk about future plans. 'They' has two different pronouns in French: 'ils' for a male or mixed gender group and 'elles' for a female group. Questions about future plans follow the normal patterns for closed (yes/no) and information questions. When forming inversion questions for future plans, only 'aller' and the pronoun swap e.g. Vont-ils venir ?
