First attested

Borrowed from
Anglo-Norman seal
Ultimate origin
Latin (signum)

Etymology

The stamp is Middle English seil, seel, borrowed from Anglo-Norman seal, borrowed from Old French seel (modern French sceau),[2][4][5] from Vulgar Latin *sigellum,[2][5] from Latin sigillum (“small picture, engraved figure, seal”), a diminutive of signum (“mark, token, sign”) (see sign).[2][5][4][6] The Latin word was also borrowed into Gothic, German Siegel and Dutch zegel, and an earlier borrowing into Old English is insegel.[2][5] The verb is from the noun or from Old French seeler.[5][4][7]

Earliest recorded meaning

Figuratively, something that joins two things: probably about 1200;[2] an official seal, an authenticating mark, from 1258.[2][8] Etymonline has the design stamped on wax from about 1200.[5]

Semantic evolution

The engraved device used to make the impression, technically a matrix, is by about 1300.[5] Further senses come from a seal marking and closing a document to keep it secret (about 1300),[5] and an identifying mark, especially one confirming goods or measures as standard, is from the mid-14th century.[5] The verb meant to fasten with a seal or to join together from about 1200,[5] and to conclude or ratify from the late 15th century.[5] To close a jar or container with wax, lead or cement is from the 1660s,[5] and something that stops a gas or liquid from escaping from 1853.[5] To seal one's lips is by 1782 and to seal one's fate from 1799.[5] Put the seal on and set one's seal to come from the stamping of documents, and seal off from seals showing that something has not been opened.[6] Sealing wax is attested from about 1300.[5]

Inherited
First attested
before 899
Inherited from
Old English seolh
Ultimate origin
Proto-Germanic (*selhaz)

Etymology

The animal is Middle English sele, inherited from Old English seolh (stem sēol-),[2][4][5] from Proto-Germanic *selhaz,[2][5] which is also the source of Middle Low German sēl, Middle Dutch seel, Old High German selah and Old Norse selr.[2][4][5] Its further origin is unknown;[4][5] Etymonline suggests a borrowing from Finnic, and Barnhart and MWU a possible link with Ancient Greek ἕλκειν (hélkein, “to drag”) or Old English sulh (“furrow”).[5][2][7]

Earliest recorded meaning

Old English sēol-, before 899, in Alfred's translation of Orosius;[2] the OED's first use is about 1000.[8] In Middle English it is sele about 1300 in Havelok the Dane, and the compound selesmer, perhaps pieces of blubber, is from 1293.[2]

Semantic evolution

The Anglo-Saxon kenning seolhbæð, “seal's bath”, meant the sea.[5] Kinds of seal, such as eared, elephant, fur and harp seals, are named from 1781,[8] and seal short for sealskin from 1886.[8] The colour seal brown is attested by 1875, and seal point, the dark markings of a Siamese cat, from 1934.[5] The verb, to hunt seals, is from the late 18th century.[9]
