maidservant
婢 centers on a female servant or maid, specifically a woman who performs household duties in a subordinate role.
婢 combines 女 (woman) with 卑, which likely contributes both sound and the idea of low status, together meaning a female servant.
A woman 女 beside 卑, which suggests lowliness, gives the image of a maidservant doing humble work.
For ヒ, imagine a maid saying 'Hee hee' while giggling at a joke: 'Hee' -> ヒ, and she is the maidservant.
