Sisto as a Baby Name. Meaning and Origin of Sisto

What is the meaning of the name Sisto ?

The baby name Sisto is a Male name , 2 syllables long and is pronounced /ˈsiːsto/ (SEE-stoh).

Sisto is Latin in Origin.

An Italian form of the ecclesiastical name Sixtus, Sisto descends from Latin Sixtus, itself a Latinization of Greek Xystos, “polished” or “smooth.” In late antiquity the name became associated with the Latin ordinal Sextus, “sixth,” so modern sources often list both interpretations. Either way, Sisto carries a refined, classical tone grounded in early Christian usage.

Borne by five popes - Sisto I through Sisto V - the name has a distinguished Roman and Renaissance pedigree; Pope Sisto IV gave his name to the Sistine Chapel (Cappella Sistina). Sisto remains familiar in Italy, while cognates appear as Sixtus (Latin, German, and English), Sixto (Spanish and Portuguese), and Sykstus (Polish); the related Scandinavian Sixten reflects the same root. Feminine Sixta occurs in Spanish. Though rare today, Sisto offers a compact, historically resonant choice with international variants and an appealing meaning of either “polished” or “sixth.”
