amiguiña
Amiguiña is a term of endearment originating from the Galician language, primarily used in Galicia, Spain. It is a diminutive form of the word "amiga," which means "friend." The suffix "-iña" is a common diminutive in Galician, conveying affection, smallness, or endearment. Therefore, "amiguiña" translates roughly to "little friend" or "dear friend."
The term is most frequently used when addressing female friends, particularly close ones, or younger girls.
