There is no easy way to determine the gender of a French noun, so it's best to learn the noun with its corresponding article. The articles are le for masculine singular nouns, la for feminine singular nouns, and l' for any singular noun that begins with a vowel.
The preposition en is usually used when you are traveling inside of something, such as a subway.
"Tard" means late in the day or evening, whereas "en retard" means late in arriving.
Always use the verb avoir (to have) to express your physical condition (even though English uses the verb "to be.")
Endings that are generally feminine include: -ade, -ale, -ance, -ence, -ette, -ie, -ique, -oire, -sion, -tion, -ure.
Endings that are generally masculine include: -acle, -age, -al, -eau, -et, -ier, -isme, -ment.
In a mixed group of males and females, the masculine plural form always prevails. Les amis, for example, can refer to male friends or a group of male and female friends. If there are only female friends present, use les amies.
There are two ways to say "yes" in French: Use oui to answer an affirmative question, use si to answer a negative question.
Out of respect, older women in France are generally addressed as Madame (Mrs.), whether they are married or not. Mademoiselle is used for younger women.
Salut is a familiar way of saying "hello" as well as "good-bye."
French does not have separate words for who (subject) and whom (object). The word qui serves as both.
