Inherited from

Ultimate origin
Proto-Germanic *stiją

Etymology

The word for the pigpen is inherited from Middle English sti, also stie,[2][3] inherited from Old English stig, also stī, recorded with certainty only in compounds such as stīfearh (“sty-pig”),[4][2][5][6] from Proto-Germanic *stiją.[1][6][2] The Old English word is probably the same as the one meaning "hall", the first part of stigweard, steward,[4][6][7][5] though Bosworth–Toller queries the sense "hall".[8] Its cognates are Old Norse stí, in svínstí (“swine-sty”), and stía (“pen, fold”),[4][5][9] Middle Low German stege, Middle Dutch stije and modern Dutch stijg,[4][5] Danish sti and Swedish stia,[2][5] and perhaps Old High German stīga (“cattle stall”), which the OED thinks was influenced in form by another root.[4] Further back, Barnhart gives Proto-Indo-European *stāy- (“to press together”),[5] the OED a Germanic root *stī-,[4] and Merriam-Webster Unabridged suggests a link with stone.[10]

Earliest recorded meaning

An enclosure for pigs: first as an independent word about 1225, in the Ancrene Riwle,[4][5] with the line Ase swin ipund ine sti.[8] Ayto too finds no certain independent use before the 13th century,[6] but the Old English compound with fearh (“pig”) shows the sense earlier.[4][2]

Semantic evolution

A moral sense grew out of the animal's dirt early: before 1400 the word could mean an abode of moral pollution,[4] and the Middle English Dictionary records helle sti, the pit of hell.[3] Etymonline likewise dates the sense "place of filth or degradation" to the mid-15th century, with reference to Hell.[2] The application to a filthy human dwelling is from the 1590s in Etymonline and 1605 in the current OED.[2][4] Middle English also used the word for a foxhole or burrow, and perhaps for a prison cell.[3] Chaucer has it once.[11] The verb is as old as the noun: stigian (“to pen up swine”) is Old English,[4][9] Shakespeare's The Tempest applies it to confining a person,[4] and Richardson's Clarissa (1748) has the intransitive "to dwell as in a sty".[4] Johnson (1755) defines the noun as "a cabbin to keep hogs in".[12] Dialect keeps compounds such as sty-baked, of a pig coated with dirt, in Lincolnshire and Oxfordshire.[13]

sty2 swelling on the eyelid

Confidence
Probable
Formation
Back-formation
First attested
1617 Fletcher, The Mad Lover
Ultimate origin
Proto-Indo-European *steigh-

Etymology

The word for the swelling on the eyelid is probably from English a back-formation from the now obsolete styany,[4][2][15][16][9] which was misunderstood as "sty on eye",[2][15][6][14] or a shortening of the older name styan.[10][5] The form styany is in fact a compound, Middle English styanye, of styan and ye (“eye”),[17][4][14] so it first meant an eye with a styan on it.[4] Styan continues Old English stīgend,[4][9][8] literally "riser", the present participle of stīgan (“to go up, rise”) used as a noun,[4][6][9] so that the name refers to the swelling.[6][14] The verb goes back to Proto-Germanic *stīganą,[1] from Proto-Indo-European *steigh- (“to stride, step, rise”),[2][17] the root of stair.[2][6] The OED also compares Dutch stijghe, recorded by Kilian, and Norwegian stig.[4][18]

Earliest recorded meaning

An inflamed swelling on the eyelid: 1617, as stye, in John Fletcher's The Mad Lover.[5][10][19] The current OED dates the same text to before 1625.[4]

Semantic evolution

Old English stīgend already translated the Latin medical term in a glossary,[8][4] and styan and styany lived on in dialect after the shorter form had taken over.[9] The English Dialect Dictionary finds the word from Northumberland to Lincolnshire and Northamptonshire, in spellings such as stigh, stee and stay.[13]

Timeline

  • c. 1000 – Old English form, glossing the medical term for the swelling.[19][8]
  • c. 1440 – styany, in the Promptorium Parvulorum.[4][5]
  • 1601 – the spelling styan.[5]
  • 1617 – stye.[5][10][19]

Meanings

Noun

  1. An inflamed swelling of a sebaceous gland at the edge of the eyelid, usually caused by bacteria; technically a hordeolum.[14][10][9]

Usage notes

The eyelid word is often spelled stye, as a variant,[10] and Collins gives that spelling first.[14] English once had further words of this spelling, all now obsolete or dialectal: a verb meaning to climb, from Old English stīgan;[10][2][4] a noun meaning a path, from Old English stīg;[4][9][8] and a noun meaning a ladder, from Old Norse stige.[4]
