A female foster parent; a woman who raises and cares for a child not biologically her own.
From foster plus the feminine suffix -ess. Older terminology reflecting gender-specific noun formations in English.
Historical records show many famous fostresses—like the women who nursed Viking children—often had more influence on future leaders than biological mothers ever did!
The -ess suffix marks female gender as marked/exceptional. 'Fostress' unnecessarily genders a role that is gender-neutral in function (foster caregiver). Marks woman's role as derivative from male norm.
Use 'fosterer' or 'foster parent' for all genders. Reserve gendered terms for contexts where biological sex is specifically relevant.

Women have historically performed foster care and child-rearing labor—often unpaid or undervalued. Using gender-neutral terminology recognizes this work as a skilled role, not a feminine default.
