Pronunciation

  • /ˈbuː.tɑn/[1]

Forms

būtan[1]

Etymology

It is inherited from Proto-West Germanic *biūtan, formed from *bī (“by”) and *ūtan, the dative of *ūtō (“outside”).[1] Within Old English it corresponds to be- and ūtan (“from outside”), as Bosworth and Toller, Holthausen and Köbler analyse it.[2][3][4] The same formation is found in Old Frisian būta, Old Saxon biūtan and Old High German biūzan,[4] and in Dutch buiten.[3]

The adverb *ūt (“out”) behind it continues Proto-Indo-European *úd (“out”), its vowel lengthened because the word was a monosyllable.[5]

Earliest recorded meaning

The earliest dated record is a charter of King Æthelberht of 858, surviving in a contemporary single sheet: the land at Mersham was made folkland butan ðem merscum & butan ðem sealtern et Fefresham “except for the marshes and except for the salt-works at Faversham”.[6][7] The Vespasian Psalter gloss of the mid-ninth century has butan intingan “without cause” for Latin “sine causa”.[8][7]

Semantic evolution

As a preposition with the dative, rarely the accusative, it first meant “outside of, out of” (bútan ðære wícstówe “outside the camp”), and then “without” and “except”.[2][9] As a conjunction it means “unless” with the subjunctive and “except that” with the indicative.[2][10] After a negative it came to mean “only”: ne … būton “nothing but”.[3][11] In glosses it renders Latin sine, praeter, extra and nisi.[4] The spelling būton is the usual one in the laws.[11]

Etymonline notes that it was not used for “on the contrary” until late Old English.[12] It continued as Middle English but, now English but.[12]
