Manuelito is of Spanish origin, derived from the given name Manuel. It is a diminutive form, often used as an affectionate nickname or familiar form of address for someone named Manuel. The name Manuel itself means "God is with us" and is of Hebrew origin. Manuelito is typically used within Spanish-speaking communities and is often found in parts of South America, Central America, and the southern regions of North America. It is also sometimes used as a given name on its own, rather than just a diminutive form. However, it is more commonly used as a term of endearment or familiarity for someone named Manuel.
"Manuelito experienced a peak in popularity between 1974 and 1980, with over 60 births annually during this period. However, there was a significant decline afterwards, with fewer than 10 births per year from 1982 onwards."
