Usage of le/la/les
In sentences such as "wine is my alcohol", why is the word "le" required before my sentence (why "le vin est mon alcool" rather than "vin est mon alcool")? When should I use le/la/les and when not?
In addition, in french, you don't say nouns with no article before. In this case, you need to use le because it is a start of a sentence and in most cases you put Le La les l' in the start of a sentence if there is a noun.
Le/la/les are articles in french (similar to English's an,a or the) except they are used with almost every noun. You use les if the noun is plural, le if it is singular male, and la if it is singular female. All nouns in french are either male or female.
French requires an article at the start of a sentence, and when there is no definite article for a noun eg "Je mange du pain" not "Je mange pain". It's like saying "I eat some bread". Du (de + le) = masculine De la = feminine
Nouns in french don't come without an article. Wine (Singular) translates to "le vin". The same applies when a noun is in the middle or the end of a sentence. It is not Je veux vin, it is Je veux DU vin. (I want wine)
