What french word starts with the letter k?

There are no common French words that start with the letter "k".

This is because French orthography, unlike English, generally doesn't use "k" at the beginning of words. The sound represented by "k" is usually spelled with "c" or "qu".

For example:

* "k" sound at the beginning of a word:

* "car" (car) is spelled "voiture"

* "kite" (kite) is spelled "cerf-volant"

However, there are some borrowed words from other languages, primarily English, that retain the "k" spelling:

* "ketchup" (ketchup) - *ketchup*

* "kilogramme" (kilogram) - *kilogramme*

* "kangourou" (kangaroo) - *kangourou*

These words are considered loanwords and are often pronounced with a "k" sound that is similar to the English pronunciation.
