Anaisá is of Brazilian origin, derived from the Tupi-Guarani words 'ana' meaning 'flower' and 'isá' signifying 'the dawn'. This name gained popularity in Brazil during the mid-20th century and has since been embraced by other Portuguese-speaking countries. It carries a melodic rhythm, with its stress falling on the second syllable: Ah-nah-EE-sah. The use of the accent grave over the 'a' is characteristic of Brazilian Portuguese orthography.
"The name Anaisa has seen varying popularity over the years, with a significant spike occurring between 1992 and 1995, reaching its peak at 42 births in 1993. After 2008, the number of annual births consistently fluctuated between single digits until a recent surge in popularity, with 18 births recorded both in 2022 and 2023."
