abscisi

Abscisi is not a widely recognized term in major scientific or mathematical glossaries. It does not denote a distinct concept on its own in standard references. In written material, it can appear as a misspelling, a typographical error, or as an attempt at forming the plural of a related Latin-derived word.

One plausible source of confusion is abscissa, the x-coordinate in a Cartesian coordinate system. The standard plural forms of abscissa are abscissae (classical usage) or abscissas (common modern usage); abscisi is not an accepted plural in conventional terminology.

Another potential confusion arises with abscission, a biological process in which plant parts such as leaves, fruits, or petals are shed. Abscission involves a specialized abscission zone and an abscission layer where cell separation occurs, often regulated by hormonal signals and environmental factors. The term abscission describes the phenomenon, not a plural form like abscisi.

Etymology: both abscissa and abscission derive from Latin roots related to cutting off or separation (from ab- “away” and caedere “to cut”).
