What does fostress mean?
Fostress is a rare, chiefly archaic noun denoting a woman who serves as a foster mother: someone responsible for the care and upbringing of a child who is not her own. In older usage, the word could also describe a woman who acted more generally as a nurse, guardian, or rearer of children, so its historical sense was sometimes broader than the modern legal concept of foster care. The term is found much more often in older literature than in present-day speech. Contemporary writers normally choose foster parent when gender is irrelevant or foster mother when it is relevant. Fostress remains useful chiefly for readers of historical or literary texts, where it conveys an explicitly female, nurturing role. Its rarity also means that many modern speakers encounter the word for the first time and may initially mistake it for a feminine form of foster or for a term connected to fostering in general.
nounA woman who acts as a foster parent by caring for and bringing up a child who is not her own. Historically, the term could also refer more broadly to a woman who nursed or reared children.
- A woman who serves as a foster parent, caring for and bringing up a child who is not her own.
- Chiefly historical: a woman who acts as a nurse, guardian, or rearer of children.
"She remained the children's fostress throughout their years at the country house."
"After the child's parents died, his aunt became his fostress."
"In the old letters, the governess is repeatedly described as the young princes' fostress."
The regular plural is rarely encountered because the word itself is now uncommon.
"The novel portrays two fostresses who transform the lives of their respective families."
Fostress preserves the old feminine ending -ess, making it a vivid reminder of how English once marked the gender of a person fulfilling a caring role.

Where does fostress come from?
Fostress is an English formation made by adding the feminine agent suffix -ess to foster. Foster passed into Middle English from Old French and historically covered the care or upbringing of a child as well as the person performing that role. The suffix -ess reflects a long-established English pattern of marking female agents, a contrast that modern usage generally avoids with the gender-neutral expression foster parent.
How fostress is actually used
This is a rare, chiefly archaic or literary word. In modern English, foster parent or foster mother is usual, and the gender-specific term may sound restrictive or period-specific.
Easily confused with fostress
