Definition: Quintus is a Latin word meaning "eight," often used as a diminutive form to denote an older or female relative. The term has numerous meanings across various cultural contexts, but the most common use in English comes from the Greek ĪÎĩĪΚĪĪĪ ĪÎŽĪ (periptechia), which refers to a woman's pregnancy and childbirth. For instance, in the Old Testament (Psalm 86:13-27) and New Testament (Luke 11:19), quintus is used as a noun referring to someone eight years old or older. It is also often used figuratively for a younger sibling, such as in the context of brothers or sisters. Understanding Quintus requires a good understanding of Greek terms. If you want a more precise definition and example usage, I would recommend looking up those specific verses from the New Testament in your Bible.
