A child raised by foster parents; a fostered or adopted child.
From foster plus the diminutive suffix -ling, originally meaning 'little foster child.' Common in Middle English and still used in modern literature.
In Shakespeare's time, 'fosterling' wasn't seen as shameful at all—it was prestigious for noble children to be fostered by other families as part of their education!
