What does jetty mean?
A jetty is a narrow structure built from a shore into a river, lake, or sea. It commonly serves as a landing stage for small boats, a place for ferry passengers to wait, or a sheltered point from which vessels can be boarded. Jetty often suggests a relatively modest, functional structure, such as a wooden landing beside a harbor, though the term can also apply to larger masonry structures. The word is used in both British and American English and is especially associated with coastal, harbor, and inland-water settings. British speakers commonly pronounce it with an “e” sound in the first syllable, while American pronunciation often uses a long “a” sound. Although “pier” is a close synonym, it is broader in meaning and can refer to a larger structure extending from land into water. A jetty more specifically evokes a landing platform or structure associated with boats and people arriving or departing.
A structure projecting from a shore into water, used as a landing place for boats or as a place for passengers to board and disembark.
"Small boats tied up alongside the jetty throughout the day."
Often used for a relatively narrow landing stage, but the term is not restricted to wooden structures.
To furnish with a jetty or connect something with a jetty.
"The shore was jettied to accommodate the growing trade."
Obsolete and rare; modern usage is overwhelmingly noun-based.
The standard plural changes the final “y” to “i” before “-es.”
"Several stone jetties line the edge of the estuary."
The word jetty preserves the idea of something thrown out: its French ancestor literally means “thrown” or “projected.”

Where does jetty come from?
Jetty comes from the French jetée, the feminine past participle of jeter, meaning “thrown” or “projected,” referring to a structure projected into water. The French verb derives from Old French jeter and ultimately from Vulgar Latin jactare, a frequentative form of Latin jacere, “to throw.” English borrowed the word in the early modern period; related English words include jet, jettison, and jetsam, while jeté in ballet also preserves the same French root.
How jetty is actually used
Jetty is standard in both British and American English, although it is especially common in British coastal and maritime speech. In American pronunciation, the first vowel is often pronounced as a long “a” sound rather than the “e” sound heard in the standard British pronunciation.
