"Tout" has four possible forms:
- masculine: singular "tout" plural "tous"
- feminine: singular "toute" plural "toutes"
"Tout" can be a noun, an adjective, a pronoun, or an adverb.
- noun: "le tout" (invariable)
- adjective: "tout" (masc. sg), "toute" (fem. sg), "tous" (masc. pl), "toutes" (fem. pl)
- pronoun: "tous" (masc. pl), "toutes" (fem. pl), "tout" (invariable)
- adverb: "tout" (masc. sg and pl), "toute" (fem. sg), "toutes" (fem. pl)
Difference in pronunciation:
- "tout": the final "t" is not pronounced
- "tous": the final "s" is pronounced (right now it is not pronounced, because there is an audio problem in our system that we will fix as soon as possible).
The gender of the adverb follows the gender and number or the subject (with one exception), see:
- "Il est tout seul." (masc. sg) means "He is all alone".
- "Elle est toute seule." (fem. sg) means "She is all alone".
- "Ils sont tout seuls." (masc. pl) means "They are all alone". (NOTE: in the plural form, the masc pl adverb does not have a final "s")
- "Elles sont toutes seules." (fem. pl) means "They are all alone".
I got a version of the question that forced me to choose between good morning all and good afternoon all and it only allowed good morning. My French wife confirmed that it doesn't really match either, it is most accurately good day to all of something like that. And if you are forced to choose between morning or afternoon there is no indication of which it is besides context.
Yes I know, I'm working with french people for 20 years and I'm fluent in french, I only use this app to improve my writing... Anyway, "bonjour" can be translated as hallo, good morning or good afternoon, since there is no adecvate translation in english. Just like good afternoon is bon apres-midi, good morning should be bon matin, but the french people never use it, instead they use bonjour as a greeting, not limited to morning...
