Seliba Sa Boithuto is an expression in Sesotho (the language spoken by Basotho in Lesotho and parts of South Africa). Seliba means Spring in English. Boithuto is derived from the verb ho ruta (to teach). Ho ruta with the prefix "i" becomes ho ithuta, which means to teach yourself: to study. The prefix "bo" makes the verb into an abstract noun, therefore boithuto means self study.
Therefore, Seliba Sa Boithuto means the Source of Studying by yourself
