What does fostress mean?
A fostress is a woman who takes on the care and upbringing of a child that is not her own by birth — in effect, a female foster parent. The term belongs to an older vocabulary of childcare, formed by attaching the feminine suffix -ess to the noun foster, which since Anglo-Saxon times has described the nurturing of another's child. In medieval and early modern England, fostering out children to nurses and carers was common practice among noble and gentry families, and the fostress appears in ballads, romances, and household records as the woman who secretly suckled, raised, or sheltered a child of uncertain or concealed parentage. Today the word is rarely encountered outside historical and literary contexts, having been superseded by gender-neutral terms such as foster carer and foster parent. Its survival offers a glimpse into how language once marked the gendered division of caregiving roles.
nounA fostress is a woman who acts as a foster parent, rearing or caring for a child that is not her own by birth; more broadly, a female fosterer of a child.
- A woman who fosters or brings up a child not her own by birth.
- (Historical/literary) A female nurse or wet-nurse entrusted with an infant's upbringing.
"The orphaned heir was raised in secret by a humble fostress in the village."
"After the plague took both parents, the girl was taken in by a kind fostress from the next parish."
"In the old ballad, the king's daughter is suckled and raised by a lowly fostress who never reveals her royal birth."
Pluralizes regularly by adding -es, like other -ess nouns (e.g., actresses, lionesses).
"The parish records name several fostresses who cared for foundlings in the eighteenth century."
Long before modern foster care systems existed, English already had a word for the women who quietly raised other people's children — the fostress.

Etymology of fostress
The word combines "foster," from Old English fōstor meaning nourishment or the rearing of another's child, with the feminine suffix -ess, which was adopted into English from Old French in the medieval period to create female forms of agent nouns (as in actress, tigress). The underlying root connects it to Old English words for feeding and nourishment, including those that gave rise to modern "food" and "fodder." As -ess forms declined after the nineteenth century, "fostress" likewise fell into disuse.
How fostress is actually used
"Fostress" is a rare, largely historical term carrying the feminine suffix -ess, which fell out of fashion during the twentieth century as gendered occupational titles were replaced by neutral ones. It survives chiefly in older literature and genealogical writing; in contemporary usage "foster mother" or "foster carer" is strongly preferred.
Easily confused with fostress
"Foster" is the general term for someone (or something) that nurtures another without being its biological parent, while "fostress" specifically denotes a female such caregiver.
