The French verb jeter means “to throw”, “to cast”, “to toss”, or at times “to put” or “to send”. The noun une jetée has more than one use, but today it most often means a pier, breakwater, or long built structure that projects into water. The two words are related. Jetée comes from the same word family as jeter, and the link between them becomes easier to see once one looks at their older meanings.

The root behind both words

Both words go back to Latin iactare, which meant “to throw often”, “to toss about”, or “to hurl”. Through changes over time, Old French developed forms such as jeter.

The basic idea behind the word family was motion through throwing or casting.

From jeter came many French nouns:

• jet = throw, burst, stream, spray
• rejet = rejection, waste, throwback
• trajet = route, course, journey
• projet = plan, project
• jeton = token
• jetée = thing thrown or cast

The ending -ée often turns a verb into a noun that names the result of an act or the thing produced by it.

Examples:

• Une poignée from poigner “a handful”
• Une montée from monter “a climb” or “an ascent”
• Une arrivée from arriver “an arrival”

So jetée first meant something like “that which has been thrown” or “that which has been cast out”.

How a “thrown thing” became a pier

The modern meaning of jetée as a pier or breakwater came from building methods.

To make a barrier in water, workers once dumped or threw large amounts of stone, earth, timber, and other material into the sea or river. This mass of thrown material formed a structure that pushed out into the water.

So the chain of meaning was roughly:

• throw
• thrown material
• built mass of thrown material
• pier or breakwater

English had a similar path in some old building terms. Many building words began as descriptions of actions.

The old sense of jetée as “thing thrown” faded, while the harbour meaning stayed alive.

Examples:

• Le bateau est amarré près de la jetée. “The boat is tied near the pier.”
• Nous avons marché jusqu’à la jetée. “We walked to the pier.”
• Les vagues frappaient la jetée. “The waves struck the breakwater.”
• La jetée protège le port. “The breakwater protects the harbour.”

The direct use of jeter

The verb itself still keeps its old core sense of throwing.

Examples:

• Il a jeté la balle. “He threw the ball.”
• Elle a jeté les clés sur la table. “She threw the keys onto the table.”
• Ne jetez pas ces papiers. “Do not throw away those papers.”
• Ils ont jeté des pierres dans la rivière. “They threw stones into the river.”

French also uses jeter in many less direct ways.

Examples:

• Jeter un regard “To cast a glance”
• Jeter un coup d’œil “To take a quick look”
• Jeter le doute “To cast doubt”
• Jeter les bases “To lay the foundations”
• Jeter l’argent par les fenêtres “To throw money away”

The old idea of throwing or sending outward still lies under these uses.

Other meanings of jetée

Besides the harbour sense, jetée has had other uses.

In dance, especially ballet, a jeté is a leap in which the dancer seems to throw the body through space.

There was also an older use of jetée in building and military works for something projecting outward.

The sense of projection remains the common thread.

Related words in the same family

Many French words from this family no longer make the idea of throwing obvious.

Jet

Examples:

• Un jet d’eau “A water jet”
• Un jet de vapeur “A burst of steam”
• Le jet de lumière traversait la pièce. “The beam of light crossed the room.”

Originally this was the act or result of throwing.

Projet

Today projet means “project” or “plan”, but Latin proicere meant “to throw forward”.

Examples:

• Son projet a été accepté. “His project was accepted.”
• Nous travaillons sur un nouveau projet. “We are working on a new project.”

Trajet

Trajet comes from the idea of throwing across.

Examples:

• Le trajet dure une heure. “The journey lasts one hour.”
• Le trajet était très long. “The trip was very long.”

Examples:

• Le rejet de sa demande l’a surpris. “The rejection of his request surprised him.”
