Here's why:
* Swahili naming conventions often reflect cultural values and traditions.
* There's no established Swahili equivalent for the name "Jessica."
However, you could consider these options:
* Choose a Swahili name with a similar meaning or sound: You could find a Swahili name that has a meaning related to "Jessica," such as "Jesika" (meaning "gift of God").
* Use a Swahili nickname: You could use a Swahili nickname for Jessica, like "Jessy" or "Jesi."
* Simply use the name "Jessica" as it is: While not Swahili, it's a common practice to use foreign names in Swahili.
Ultimately, the best way to "say" Jessica in Swahili depends on the context and your preference.
