Shamsa
Yes. Shamsa is derived from the Arabic noun 'shams' (شمس), meaning 'sun'; the form is a feminine/adjectival usage found in Arabic and in regions influenced by Arabic.
The name and its variants appear in Ottoman-era and South Asian records. While not among the most common names, it is attested in Sindh and in Ottoman-administrative regions that include Bosnian lands.
Linguistically the name evokes solar imagery. Because the well-known Sufi figure Shams al-Dīn Tabrīzī bears the masculine form, families influenced by Sufi thought sometimes choose Shamsa for its connotations of inner illumination and spiritual radiance.
Regional pet forms include 'Shamshi' or 'Shamsha' in South Asian vernaculars; formal variants include 'Shamsah' or 'Shamsiya'.
Pronunciation common in Arabic and regional use is 'SHAM-sa' (IPA: ˈʃam.sa), with a short vowel on the second syllable.
