Middle High German warumbe

Pronunciation

  • /vaˈʁʊm/, /ˈvaː.ʁʊm/[1]

Forms

warum (interrogative and relative adverb, not inflected)[2][1] The spelling warumb lasted into the second half of the 17th century.[3][4] The first vowel long wavered between a and o (worumb, worum), until Adelung limited worum to the sense “about what”, which became the rule.[4]

Etymology

It is inherited from Middle High German warumbe, inherited from Old High German wārumbi, formed from Old High German wār (“where”) + umbi (“around, about”): the adverbs that became wo and um.[5][3][6] The same compound is Middle Low German warumme, Middle Dutch waeromme and Old Frisian hwerumbe, now Dutch waarom.[3][4] Unlike the modern word for “where”, it keeps the old long /aː/ and the final /r/ of the Old High German adverb.[3] Wiktionary calls it a doublet of worum that kept the older vowel, and notes that the Dutch word has both meanings.[1]

Earliest recorded meaning

The compound appears only in late Old High German, first in Notker around 1000;[4][3] Kluge dates it to the 11th century.[5] Already in Middle High German the Central German sources assimilate it to warumme and shorten it to warumb, warum.[4]

Semantic evolution

Warum nicht as a concession is recorded from the 15th century, warum nicht gar! as an expression of firm refusal or surprise from the middle of the 18th century, and the answer warum? – darum! from the 15th or 16th century; today it serves to refuse a reason.[6] The noun das Warum “the reason” goes back to Middle High German;[6] Schopenhauer called it the mother of all sciences.[6]

Earlier warum was also used where worum is now usual, as in Lessing, and as a relative after a noun, as in Schiller's wegen des Geldes, warum ich sie ersuchte.[6] Kanzlei language of the 16th and 17th centuries had a lengthened form warumben, and in the dialects the vowel was weakened or lost.[4]

Timeline

  • About 1000 – Late Old High German wārumbi in Notker.[3][4]
  • Middle High German – The shortened forms warumme, warum appear in Central German.[4]
  • 15th century – warum nicht as a concession.[6]
  • 15th–16th century – The answer warum? – darum![6]
  • Second half of the 17th century – The spelling warumb gives way to warum.[3][4]
  • Mid-18th century – warum nicht gar![6]

Meanings

Adverb

  1. (interrogative) why, for what reason, in direct and indirect questions: Warum kommst du so spät?;[2][1] Ich verstehe nicht, warum sie gegangen ist.[2][1]
  2. (relative) For which reason: Der Grund, warum er absagte, blieb unklar.[2][7]
  3. (as a noun, das Warum) The reason: nach dem Warum fragen.[2][6]

Usage notes

Warum nicht gleich so? (colloquial) means “why not like that in the first place?”.[2] Adelung held that strictly warum asks for a purpose and so suits only beings capable of intention, though he admits the rule is seldom kept.[8]
