Etymology

The word for soft mud is inherited from Middle English wose, in the north also waise,[5][3] inherited from Old English wāse (“mud, mire”),[6][7][3][8][1] from Proto-Germanic *waisǭ.[4][7][3][9] Its cognates include Old Frisian wāse (“mud, slime”),[10][3][1] Old Saxon waso (“wet ground, mire”)[7][11] and Old Norse veisa (“stagnant pool”).[10][7][1] Barnhart, Holthausen, Orel and Merriam-Webster compare Latin vīrus (“slimy liquid, poison”),[3][12][9][8] and Etymonline assumes a root meaning "wet",[7] but the OED calls the further etymology uncertain and disputed,[10] and Köbler calls it unknown.[13] The o of the Middle English form rhymed as an open vowel through the 16th century; the modern vowel shows raising after w, probably helped by association with ooze2,[10][14] and the w itself was then lost.[10][15] The spelling without it is recorded from the mid-16th century.[3][7][14]

Earliest recorded meaning

Wet mud or slime: first recorded in the Corpus Glossary,[10] before 800 in Barnhart's dating.[3][16] Old English glossaries use it for Latin caenum (“mud, filth”), once beside fen.[17][18]

Semantic evolution

In Old English the word already appears in charters for land in northern Berkshire, of a marsh or a stream;[17][18][10] one such Wase is now Osse Ditch.[10] Middle English used it for slime in general, for the mud of the sea bottom or an estuary, and for the clay from which humans were made.[5] The Ayenbite of Inwyt (1340) says that the sinner sleeps in his sin as the swine does "ine þe wose",[5][3] and Piers Plowman has "Right as weodes wexen in wose and in donge".[5][15] From before 1500 until 1867 it could also name a single stretch of mud or marsh.[10][1] Johnson (1755), who offered a derivation either from the French for waters or from the Old English for wetness, defined it as soft mud at the bottom of water, quoting Shakespeare's "My son i' th' ooze is bedded".[19] A verb meaning to bury in ooze, or to spread ooze on a field, was used from 1729 to 1777.[10] The scientific sense comes from 1858, in Dayman's Deep Sea Soundings: the fine mud of the ocean floor, made up of the shells of microscopic organisms.[10][1]

Etymology

The word for juice and sap is inherited from Middle English wose,[3][8] inherited from Old English wōs (“juice, moisture”),[6][7][3][1][17] from Proto-Germanic *wōsą.[4][7][3][9] Its cognates include Middle Low German wōs (“foam, scum”),[10][3][1] Old Swedish ōs and Old Danish ōs (“juice from a plant”).[10] The OED calls the further etymology uncertain and disputed, and thinks it probably unrelated to Old Norse vás (“wetness”),[10] which the Shorter Oxford and Hoad set beside it.[1][2] Barnhart takes it back to Proto-Indo-European *wes- (“wet”),[3] which Köbler does with a query.[13] Etymonline and Holthausen connect it with the Old English word for mud, ooze1.[7][12] The verb is inherited from Middle English wosen, formed from the noun according to the OED, Merriam-Webster, Barnhart and Etymonline.[10][8][3][7] The MED instead derives it from wōsan, a Northumbrian variant of wēsan,[5] but the OED found no evidence for that form.[10] The later noun for a slow flow comes from the verb.[10][3][1] The spelling without w, with the initial consonant lost before the vowel, is recorded from the late 16th century.[3][7][10]

Earliest recorded meaning

Juice, sap: the noun is first recorded in the Leechbook,[10] about 1000 in Barnhart's dating.[3] Old English medical recipes tell the reader to crush a plant and "wring ðæt wós", press out the juice.[17] The verb is first recorded before 1387, in Trevisa's translation of Higden's Polychronicon, for giving out liquid slowly.[10][3]

Semantic evolution

The Old English noun was used in medical recipes for the liquid pressed from plants;[17][10] in this sense it now survives only in northern English regional use.[10] A specialized use for the liquor of a tanner's vat, an infusion of oak bark or sumac, is recorded before 1450 by the OED,[10] but only in the 16th century by Hoad and the Shorter Oxford,[2][1] and it gave ooze leather.[10][20] The verb has had the sense of liquid passing through pores since the late 14th century, when Trevisa wrote of water that "woseþ oute" of the earth.[5][10] Figurative uses begin in the late 18th century, when Sheridan used it of an immaterial quality leaking away (1775).[10] Air, light and sound could ooze from 1824, in Washington Irving, and people from 1847, in Dickens;[10] American slang has the verb for walking or leaving casually or furtively from 1900.[21] Since 1889 a person or thing may also ooze a quality, giving a strong impression of it,[10] and since 1962 one may ooze a remark, saying it in an unctuous or sneering way.[10] Johnson (1755) took "soft flow; spring" as the meaning of the noun in Prior, whose poem of 1718 is the first record of the noun for a slow flow.[19][10][3]

Timeline

  • c. 1000 – juice, sap.[10][3]
  • before 1387 – verb, to give out liquid slowly, as wosen.[10][3][5]
  • before 1398 – verb, of liquid, to pass slowly through pores or openings; of a substance, to exude moisture.[10][5]
  • before 1450 – the liquor of a tanning vat.[10] Merriam-Webster dates it to 1587.[8]
  • 1718 – noun, a slow flow; something that oozes.[10][3]
  • 1775 – verb, of an immaterial quality, to leak away gradually.[10]
  • 1847 – verb, of a person, to move slowly or stealthily.[10]
  • 1889 – verb, to give a strong impression of a quality.[10]
  • 1916 – noun, ooze leather.[10]

Usage notes

A rare, obsolete ooze meaning seaweed, recorded from about 1475 to 1833, is of uncertain origin; the MED takes it as probably a use of wase (“bundle, bunch”), while the OED suggests it may be the word for mud.[10][1][5] In Scots, ooze was also the nap or fluff that falls from yarn or cloth, and fibre put into an inkstand to keep the ink from spilling.[22]
