Diminutive for "hermana." The ending "-ita/-ica(s)" or "-ito/-ico(s)" can be added to the end of nouns (casa - casita; amigos - amiguitos; etc.) or adjectives (clara - clarita; quieto - quietico; etc.), making the translation more familiar or affectionate, or implying to a lesser extent or in a smaller quantity in some cases.
