剣(けん) • (Ken) 

1. a male given name

⟨turuki₁⟩ → */turukʲi/ → /t͡suruɡi/

Shift from Old Japanese turuki,[1][2] itself of unknown derivation.

A surface analysis suggests that this might be a compound of 釣る, 吊る (tsuru, “to hang, as at one's side”) + ki, but there is no clear etymon for the ki portion. One possibility would be 牙 (“fang”), read as kiba in modern Japanese but also appearing as ki in Old Japanese contexts. Such usage might parallel the combined tooth and blade meanings of the term ha, spelled more specifically as 歯 (“tooth”) and 刃 (“blade”), with these two senses listed as cognates in Japanese dictionaries.[1][2]

More tentative suggestions have been connections to Austronesian, such as Tagalog suligi (“dart, short spear”) (Can this⁽⁺⁾ etymology be sourced?), but such possibilities seem only speculative at present.

• (Tokyo) つるぎ [tsùrúgí] (Heiban – [0])[1]

剣(つるぎ) • (tsurugi) 

1. a sword

This term usually refers more specifically to double-edged swords, as opposed to the single-edged 刀 (katana).[2]

剣(つるぎ) • (Tsurugi) 

1. a female given name
2. a surname

Unknown. Japanese names often apply readings from other words to allude to different meanings.

• IPA^(key): [ma̠ja̠ka̠]

剣(まやか) • (Mayaka) 

1. a female given name

剣(つとむ) • (Tsutomu) 

1. a male given name

• 諸(もろ)刃(は) (moroha, “double edge”)

The variation between turugi₁ or turuki₁ suggests a compound origin. Alternatively, it may possibly be a misspelling of turugi₁, as there was not a phonemic distinction of voiced and voiceless consonants in most Old Japanese texts. However, turuki₁ is attested in the Nihon Shoki.

A surface analysis suggests that this might be a compound of 釣る, 吊る (turu, “to hang, as at one's side”) + ki, but there is no clear etymon for the ki portion. One possibility would be 牙 (KI, “fang”), in spite that KI is not attested phonographically in Old Japanese. Such usage might parallel the combined tooth and blade meanings of the term ha, spelled more specifically as 歯 (“tooth”) and 刃 (“blade”), with these two senses listed as cognates in Japanese dictionaries.[1][2]
