Meaning

  1. omen, sign, harbinger, portent, token (an object or occurrence believed to portend or predict a future event, circumstance, situation, or state of affairs)
    […] Quod omen res consecuta est; ipsa enim brevi mortua est, virgo autem nupsit, cui Caecilia nupta fuerat. Haec posse contemni vel etiam rideri praeclare intellego, sed id ipsum est deos non putare, quae ab iis significantur, contemnere.[…] And this was a sign of what came to pass, for in a short time Caecilia died and the girl married her aunt's husband. I realize perfectly well that these omens may be lightly regarded and even be laughed at, but to make light of signs sent by the gods is nothing less than to disbelieve in the existence of the gods.45 BCE, Cicero, De divinatione 1.46.104
    non cedit Veiiento, sed ut fanaticus oestro / percussus, Bellona, tuo diuinat et "ingens / omen habes" inquit "magni clarique triumphi..."Veiientus yields not, but as one inspired by the maddening / influence of the goddess Bellona, prophesies. "A mighty / token this you possess" he says "of some great and illustrious triumph..."c. 101 CE, Juvenalis, Saturae 4.123–125

Choosing the right word Döderlein's Latin Synonyms

Auguria · Auspicia · Prodigia · Ostenta · Portenta · Monstra · Omina

Auguria and auspicia are appearances in the ordinary course of nature, which for the most part possess a meaning for those only who are skilful in the interpretation of signs; auguria (from augur, αὐγάζειν) for the members of the college of augurs, who are skilled in such things; auspicia, for the magistrates, who have the right to take auspices: whereas prodigia, ostenta, portenta, monstra, are appearances out of the ordinary course of nature, which strike the common people, and only receive a more exact interpretation from the soothsayer: lastly, omina (ὄθματα, ὄσσαι) are signs which any person, to whom they occur, can interpret for himself, without assistance. The primary notion in prodigium is, that the appearance is replete with meaning, and pregnant with consequences; in ostentum, that it excites wonder, and is great in its nature: in portentum, that it excites terror, and threatens danger; in monstrum, that it is unnatural and ugly. (v. 178.)

Origins

From Old Latin osmen, of uncertain origin, with many origins proposed: * Ancient authors derived it from ōs (“mouth”). * Derived from Proto-Indo-European *h₂ew- (“to see, perceive”), whence audiō and Ancient Greek οἴομαι (oíomai, “to think, believe, suppose”). * Per Beneviste and Oettinger, connected to Hittite [script needed] (hā-ᶻᶦ, “to believe, trust”) via a supposed Proto-Indo-European *h₂e/oh₃-s-mn (“trust”). De Vaan considers this semantically unconvincing. * Per De Vaan (who doubts the authenticity of the Old Latin form osmen), most likely from Proto-Italic *okʷsmn- (“sighting, omen”), from an s-present form of Proto-Indo-European *h₃ekʷ- (“to see; eye”) + *-men (whence -men). * An alternative theory by Meier-Brügger derives the word from Proto-Indo-European *Hoǵ-smen (“speech, what was predicted”), from an o-grade of Proto-Indo-European *h₁eǵ- (“to say”) (whence aiō (“id”)). This is semantically attractive, but requires the existence of the otherwise unattested-in-Latin o-grade of aiō, as well as an atypical formation of a smen-derivative from the Proto-Indo-European perfect *He-Hoǵ-.
