Laïssa

The name Laïssa is believed to be a variant of the Greek name Laïs, which means 'joyful' or 'happy'. It has a long history, with roots in ancient Greece. While not as common as some other Greek names, it has maintained a presence, particularly in regions with strong Greek cultural influence. The diacritic mark (tréma) over the 'i' in Laïssa is often used in French and Portuguese to indicate that the 'i' should be pronounced separately from the preceding vowel, preventing it from forming a diphthong.

Its usage has seen fluctuations over time and across different cultures. In some contexts, it might be a diminutive or a regional variant of other names. The name carries a positive connotation due to its meaning, associating it with happiness and cheerfulness.
