This is because the French language does not have the sound "w" at the beginning of words.
However, there are a few exceptions to this rule:
* Loanwords: French has borrowed some words from other languages that start with "w", such as "week-end", "whisky", and "watt". These words are typically spelled with a "w" and pronounced as they are in English.
* Proper nouns: There are a few proper nouns that start with "w", such as "Washington" and "William".
Therefore, while there are no "true" French words that start with "w", you might encounter the letter "w" in borrowed words and proper nouns.
