Etymology

It is inherited from Old East Slavic къ (kŭ), from Proto-Slavic *kъ.[1][2] Wiktionary and Tsyganenko set up a by-form *kъn, which survives in к нему “to him”.[1][3] The preposition is shared by all the Slavic languages: Ukrainian к (k), Belarusian к (k), Old Church Slavonic къ (kŭ), Bulgarian към (kăm) beside к (k), Serbo-Croatian ка (ka), Slovene k, Czech k, Slovak ku, Polish ku and Polabian ka.[2] Russian dialects of the Oryol and Kursk regions also have кы and ик.[2]

Vasmer relates it to an emphatic Vedic postposition placed after the dative and to Avestan kąm (“for the sake of”);[2] Tsyganenko derives it from Proto-Indo-European *ḱom.[3] Some scholars also connect Latin cum (“with”) and the Celtic prefix com-, which Vasmer leaves to Walde and Hofmann.[2] Vaillant stressed that the Slavic word was only a preposition, but Trubachev points to its use as a prefix in кудель and кудри.[2] Tsyganenko and Preobrazhensky connect the particle -ка, as in скажи-ка.[3][4]

The modern form comes from the Old Russian one through the loss of the weak jer, and the variant ко from the jer in a strong position.[3]

Earliest recorded meaning

The Izbornik of 1076 has „приде къ немоу нѣкыи оуношА красьнъ зѣло” “a very handsome youth came to him”.[5] SDRJa counts about 12,000 uses in Old Russian texts.[5]

Semantic evolution

Already in the Izbornik of 1076 the preposition marks direction in space, address to someone and a relation (“pleasing to God”); the Tale of Boris and Gleb (12th century) uses it for addition, “adding lawlessness to lawlessness”.[5] The temporal sense “towards (a time)” is in a manuscript of 1296: „къ вечероу” “towards evening”.[5] Old Russian also used it for the person something is meant for.[5] Bulgarian has replaced it largely with към.[2]

Timeline

  • 1076 – „къ немоу” “to him” in the Izbornik of 1076.[5]
  • 12th century – „побѣже къ олтарю” “ran to the altar” in the Tale of Boris and Gleb.[5]
