maid
婐 centers on a woman serving in a household: a maid or female attendant.
婐 combines 女 (woman) with 果, which likely contributes the sound. The exact historical development is uncertain, but the structure suggests a phono-semantic compound for a female role.
A woman 女 beside 果 (fruit) suggests a maid preparing or serving fruit in a household.
For ワ, imagine a maid saying 'wa!' in surprise as she drops a piece of fruit: wa -> ワ.
