tout vs tous
I'm having trouble understanding when to use "tout" and when to use "tous". Both are masculine and the vocab page given no indication if one is for plural (although how you classify "all" as plural or singular seems pretty subjective to me). Is there a rule that I'm not picking up?
"Tout" is used for uncountable objects such as bread, water, milk, time...etc
- "Il a mangé tout le pain." = "He ate all the bread."
"Tous" is used for countable objects such as lemons, eggs, apples, pens...etc
- "Prends tous tes stylos avec toi !" = "Take all your pens with you !"
To be clear, "tous" IS the plural form of the masculine "tout", just like "toutes" is the plural form of the feminine version "toute". There are no "touts". It also happens to be the case where the singular form "tout" refers to things that are uncountable. When deciding whether it is singular or plural, it is exactly like deciding the usage of "du" or "de la" instead of "des" when they all refer to "some". The same rules apply.
singular: tout le... (tout le temps, tout le pain, tout le riz)
plural: tous les... (tous les stylos, tous les jours, tous les gens, tous les amis)
neutral/genderless: tout va bien
For the masculine singular and plural, consider chocolate as a block or chocolates in a fancy box.
You ate all the chocolate = Tu as mangé tout le chocolat You ate all the chocolates = Tu as mangé tous les chocolats.
And for the feminine version, we'll consider one or more pies: You ate all the pie (that was on the table) = Tu as mangé toute la tarte You ate all the pies = Tu as mangé toutes les tartes
Et maintenant, j'ai faim. :)
