Forms

potissimum (not comparable)[1]

Etymology

It is the neuter of potissimus (“most powerful, chief”), used as an adverb.[2][1] ⟨potissimus⟩ is the superlative of potis (“able, master”), which de Vaan traces to Proto-Indo-European *pót-i- (“master, lord”), cognate with Sanskrit पति (páti-, “lord, master”), Ancient Greek πόσις (pósis, “husband”) and Lithuanian pàts (“husband”).[3]

Earliest recorded meaning

Köbler lists it in the Carmen Saliare.[4] The OLD's first citations are Plautus, Captivi: it is fitting for an innocent slave to be confident, suom apud erum potissimum, “above all before his master”.[2]

Semantic evolution

Potissimum marks one person or circumstance as particularly concerned, “especially, above all”, and one choice as preferred to every other: Plautus' haud causificor quīn eam ego habeam potissimum, “I make no excuse against having her in preference to all”.[2] It also means “in the best way” (Plautus: I'll take my revenge best by kissing).[2] Church Latin glosses it “chiefly, especially, most preferable, above all”.[5]
