Negation with Non
‘Non’ is the standard way to say ‘No’ in French, used alone or before a statement to contradict a previous claim.
c’est = it is / that is
‘c’est’ is a contraction of ‘ce + est’, used to identify or define something, often followed by a noun or date.
Definite article le with dates
When giving a full date, French uses the definite article ‘le’ before the day number (e.g., le 1er janvier).
Ordinal numbers for dates
In spoken French, the day of the month is expressed as an ordinal number without the suffix –er (except for ‘premier’). Here ‘onze’ is the cardinal form used for 11.
Month names are not capitalized
Unlike English, French month names are written in lowercase (septembre).

Cultural Tip
In France, dates are written day‑month‑year (e.g., 11/09/2024) and spoken with the day first. When mentioning historical dates like 11 September 2001, French speakers often say ‘le onze septembre deux mille un’ to avoid ambiguity. Also, be aware that ‘onze’ is pronounced with a nasal vowel, so practice the nasal /ɔ̃/ sound.
