Pronunciation

Forms

étier m (plural étiers)[1] Old French estier (1312) and ester (1400); the spelling étier dates from the end of the 17th century.[2][3]

Etymology

It is inherited from Old French estier, inherited from Latin aestuārium (“place flooded by the sea at high tide, lagoon”).[2][4][5] The TLFi describes it as a dialect word of the Atlantic coast, from the mouth of the Loire down to Gascony, and compares the place name Létier and Old Gascon esteir (“brook”) (1217).[2] The Grand Robert and the Petit Robert derive the Latin noun from aestus (“surge of the sea”).[5][6] Littré gives an intermediate Medieval Latin esterium.[7]

It is a doublet of the learned estuaire.[1][7]

Earliest recorded meaning

It is first recorded as estier in 1312, in a document of the royal archives quoted by Godefroy's Complément.[2] Littré's 14th-century quotations, from Du Cange, speak of a ditch that runs into l'estier du port below a castle and of a barge lying ou dit ester, sur l'eaue, so the word named a tidal channel that boats could use.[7]

Semantic evolution

The GLLF dates the first sense, a narrow channel linking a town with a river or the sea and able to carry small boats, to the 14th century;[3] Furetière's dictionary of 1690 adds the channel that brings sea water into the salt marshes.[3] The salt-works sense is the one the modern dictionaries give first, and Littré already called the navigational sense rare.[6][8][7]

In the mid-20th century the word came to be used on the coast of southern Brittany for a small estuary.[3] The Petit Robert labels it a regional word.[6]
