Because the verb demander takes a direct object in French.
So:
That means:
French does not use a preposition like for here the way English often does.
Examples:
Not:
It is followed by:
In your sentence:
So the structure is:
Examples:
Notice that de becomes d’ before a vowel sound:
Because au lieu de is a fixed expression. The de is required before an infinitive.
So you say:
Not:
Not exactly in this context.
The verb chiffrer can have several meanings, but here it means something like:
So au lieu de chiffrer means the landlord is asking for a quote rather than calculating or pricing it himself/herself.
This is more specialized than the basic idea of numbers. It is often used in business, construction, or budgeting contexts.
Because after au lieu de, French normally uses an infinitive when the subject stays the same in a general sense.
So:
It works like English instead of doing something, except French uses de + infinitive here.
If you wanted a full clause with a different subject, you would need a different structure, but in this sentence the infinitive is the normal choice.
This is the normal French order:
subject + verb + object + adverbial/complement
So:
French word order is often similar to English here, although the exact structures inside the sentence can differ.
A careful pronunciation would be roughly:
luh bai-yur duh-mahnd luh duh-vee oh lyuh duh shee-fray
A few useful notes:
Depending on accent and speaking speed, some vowels may sound more reduced.
It sounds fairly neutral to formal, mostly because of the vocabulary:
So the sentence would fit well in administrative, rental, repair, or business contexts. It is not slangy or casual.
