De Vaan argues that the term probably continues a stative term due to the meaning "remain." Thus, he reconstructs Proto-Indo-European *m̥néh₁yeti (“to remain”), a stative verb from *men- (“to stay, stand still”) + *-éh₁yeti. However, Schrijver argues that the expected outcome of a zero-grade form *m̥néh₁yeti would be Proto-Italic *menē-. Schrijver suggests that that the term may have borrowed the /-o-/ from the perfect form *memon-. Though, De Vaan notes that there is no other conclusive evidence in any Indo-European language for this perfect form. Regardless, Schrijver posits that the term would have then underwent the unrounding of *mo- to *ma-. De Vaan argues that it is unclear why maneō would have undergone such unrounding but not moneō. An alternative hypothesis proposed by Sihler maintains that the term developed from the pre-form Proto-Italic *menēō and added an /a/ according to the model of terms such as Latin habeō, although De Vaan argues that there is no sufficient reason for supporting such a development.
De Vaan explains the perfect form mānsī as derived from the perfect passive participle mānsus, which he argues replaced earlier *mantos. According to De Vaan, this older form may be the source of Latin mantō. Rix traces the perfect form back to a Proto-Indo-European sigmatic aorist *mḗn-s-t, whence also perhaps Ancient Greek ἔμεινα (émeina).
Related to Persian ماندن (mândan, “to remain”) and Ancient Greek μένω (ménō, “to remain”).
