Panic

nounpan·ic/ˈpæn.ɪk/

Sudden, overwhelming fear that makes people act without thinking, often a whole crowd at once.

The sudden sight of a grizzly bear filled the hiker with panic.

From French panique, from Greek panikos, “of Pan”, the god of woods and fields.87 The Greek phrase was panikon deima, “Pan fright”.7 English had it as an adjective in the late 1500s, years before the noun.87 The popular story that Pan frightened the Persians at Marathon is not in Herodotus.23

A whole page, number 1293, from an English book of 1603 in roman type, headed Of Isis and Osiris. A ring marks the words Panique affrights near the top of the page.

“…all sudden tumults and troubles of the multitude and common people, be called Panique affrights.”

Page 1293 of Philemon Holland’s English translation of Plutarch’s Morals, London, 1603, in the treatise Of Isis and Osiris. It says the Pans and Satyrs near Chemmis whispered about a crime, which is the reason for the name. Spelling is as printed; the page uses the long s, which we write as s. See the book at the Internet Archive.1

What it means today

  1. Sudden, overwhelming fear. Merriam-Webster defines it as a sudden overpowering fright, and also as sudden unreasoning terror often accompanied by mass flight.8The sudden sight of a grizzly bear filled the hiker with panic.
  2. A sudden rush of fear about money. Merriam-Webster’s noun entry includes a sudden widespread fright about financial affairs that drives values down.8 Etymonline records it by 1757.7panic buying, panic selling

There is also an adjective, with a capital letter in the dictionary: Panic, “of or relating to the god Pan”, as in Panic rites.8 The word has a second life as a plant name, but that is a different word, from Latin panicum, millet.76

Through time

Through time

English took panic as a description of a feeling before it had a noun for it. Drag the line and watch the word move from a god’s mood to a crowd’s, then to the stock market, then to one person’s bad afternoon.

How a god got the blame for a crowd

The Greek word was panikon deima, “Pan fright”, and the Greek noun panikon on its own already meant groundless fear by the time of Polybius, Cicero and Dionysius of Halicarnassus.3 An English translator in 1603 could therefore explain it in one sentence, as Holland does on the page above: the Pans and Satyrs whispered, so that all sudden mob terror is called Panique.1 That is Plutarch’s explanation, and Plutarch wrote after Polybius and Cicero had already used the word. The explanation came later than the word.

Route to English

How it traveled from Arcadia to England

123
  1. ΠάνGreek, the name of the god Pan. Wiktionary says the god has been argued to be Indo-European, and compares the Vedic Pushan, “nourisher”, a god who guarded cattle.11
  2. πανικόςGreek adjective, “of Pan”, used of groundless fear.117
  3. paniqueFrench, 15th century.7
  4. panicEnglish, an adjective about 1586 to 1600 and a noun by 1708 at the latest.87

Stops mark where each language was used. Nobody documented a single journey. Arcadia is the god’s home country, not a place the word was spoken in English.

Dates

Why the dates differ

The dictionaries mostly disagree because they are dating different parts of speech.

SourceGivesWhat it is dating
Merriam-Webster8about 1586The adjective, “resembling the state believed induced by the god Pan”.
Etymonline7about 1600The same adjective, “modifying fear, terror, etc.”.
Merriam-Webster81612The noun, a sudden unreasoning terror.
Etymonline71708The noun, “sudden mass terror”.
Merriam-Webster81780The verb.
Etymonline71827, 1902The verb, first transitive and then intransitive.

Neither page prints the early sentences, so we cannot tell why Merriam-Webster’s noun is almost a century before Etymonline’s. Holland’s page of 1603 comes after both adjective dates and before Merriam-Webster’s noun date, but it is a translation of Greek, so we do not count it as a first English use.

The myth

A myth: Pan frightened the Persians at Marathon

The word panic comes from the story that Pan scared the Persian army at Marathon.Not in Herodotus
  • Herodotus does tell of Pan at Marathon. The runner Philippides met him in the mountains above Tegea, and Pan told him to ask the Athenians why they paid him no attention, though he was of goodwill to the Athenians, had often been of service to them, and would be in the future. The Athenians later built him a precinct under the Acropolis.2 No panic, no flight of Persians.
  • A 1926 study by E. Harrison in the Classical Review asks how old the link between Pan and groundless fear really is. His answer: Pan’s name does not occur in the Iliad or the Odyssey, and Herodotus, Aeschylus and Thucydides do not connect him with fear.3
  • Harrison finds the first hint in a play, Rhesus, of doubtful date, with a line about being frightened by the trembling whip of Pan (his words, our paraphrase of the Greek).3 By Polybius’s time the noun panikon meant groundless fear all by itself, and the first writer who states the link expressly is Plutarch.3
  • Writers after Herodotus did put Pan at Marathon, but Harrison’s note on them says none of those passages has Pan striking panic into the enemy.3 The tales that do, a fight against the Titans and a ruse for Dionysus, are later, in his note citing Hyginus and Polyaenus, which we have not opened.3

The word does come from Pan. That is in every dictionary, and the dictionaries say it carefully: Merriam-Webster’s etymology is simply “French panique, from Greek panikos, literally, of Pan, from Pan”.8 It is the Marathon story that was added, probably because it is a good one.

A smaller one: Pan means “all”

The older Greek poets already made this guess. In the Homeric Hymn to Pan the gods call the baby Pan because he delighted all their hearts, which plays on the Greek word for “all”.4 Wiktionary says the grammar does not support it, since the stems differ, Πάν with the genitive Πάνος against πᾶν, πάντος.11 So panic is not “fear of everything”. It is “of Pan”.
