What does animi mean?
"Animi" is the Latin inflected form of "animus," a word denoting the mind, spirit, soul, or rational principle of a person. In classical Latin it serves as the genitive singular ('of the mind') and as the nominative and vocative plural ('minds' or 'spirits'), appearing in set phrases such as "animi causa," meaning 'for the sake of one's peace of mind.' Although it is not an independent English word, it surfaces in English texts through legal Latin, classical quotation, and older medical vocabulary, where precision of phrasing matters. The underlying root, *ane-*, meaning 'to breathe,' also gives English "animal," "animate," "unanimous," and "animosity," reflecting the ancient belief that life and thought were bound up with breath. Because it is an inflection rather than a standalone term, "animi" is best reserved for scholarly contexts; general readers will normally meet the base form "animus" instead. Its enduring interest lies in how much of our mental and emotional vocabulary descends from this single Latin root.

Etymology of animi
"Animi" derives from Latin "animus," meaning mind, spirit, courage, or breath, which in turn comes from the Proto-Indo-European root *ane-, meaning 'to breathe.' The same root produced Greek "anemos" (wind) and Sanskrit "ániti" (breathes), and via Latin it gave English "animate," "animal," "unanimity," and "animosity." In Latin usage, "animi" functions as the genitive singular and the nominative/vocative plural of "animus."
How animi is actually used
