To emphasize to whom something belongs, you can use the possessive à in one of three constructions.
In English, we use 's (apostrophe s) to indicate that one noun possesses another. The French equivalent is the preposition de, with the order of the nouns reversed.
The preposition pour usually means "for" and may be followed by a noun, pronoun, or infinitive.
A prepositional phrase, also called a compound preposition and a complex preposition, is a group of words including at least one preposition which, together, play the role of a preposition.
Prepositions are short but essential words which are placed after a verb, noun, or adjective in order to indicate a relationship between that word and the noun or pronoun that follows.
Prepositions of place indicate the location of someone or something in relation to another someone or something.
French prepositions with continents and countries depend on the gender,* number, and first letter of the name, plus of course whether you're coming or going.
French prepositions with islands and cities are easier than with other geographical names because gender plays no role. You just need to think about number (singular vs plural) and whether you're coming or going.
Generally speaking, articles are much more common in French than in English, but there are exceptions, such as when certain prepositions are followed by nouns.
French prepositions with regions, departments, provinces, states, and counties depend on the gender* and first letter of the name, plus of course whether you're coming or going.
For quantities, adjectives, and prepositional phrases, the question of de vs du, de la, des depends on whether the noun that follows is specific or unspecific.
The preposition sans is used similarly to its English equivalent "without," but not without a few differences.
The preposition sur is often equivalent to "on" but has many other possible translations.
