In 10.30.12, her origin as a river goddess may explain her invocation as a protective deity in a hymn to the celestial waters. In 10.135.5, as Indra drinks Soma he is described as refreshed by Sarasvati. The invocations in 10.17 address Sarasvati as a goddess of the forefathers as well as of the present generation. In 1.13, 1.89, 10.85, 10.66 and 10.141, she is listed with other gods and goddesses, not with rivers. In 10.65, she is invoked together with "holy thoughts" (') and "munificence" ('), consistent with her role as a goddess of both knowledge and fertility.
