Chai

Origin & Etymology

Chai comes from the Hebrew word חַי (chai), meaning alive or life. In Jewish tradition, it is one of the most powerful and auspicious words, appearing in the religious toast L'chaim (to life!). The number 18 is considered lucky in Jewish culture because the Hebrew letters chet and yod — which spell chai — have numerical values of 8 and 10. The word is so revered that Jews often give charitable gifts in multiples of 18.

Popularity Story

Chai as a given name is rare but growing among Jewish families and spiritually-minded parents who appreciate its profound meaning. It is distinct from the popular Kai, offering similar sounds with deeper cultural roots.

Cultural Significance

In Jewish culture, chai is one of the most sacred symbols of life and vitality. The word appears on mezuzot, jewelry, and in blessings. Giving someone chai or a multiple of 18 dollars is considered a blessing of life and prosperity.
