⟨tu⟩ → /t͡su/

From Old Japanese.

There were some variants found in the old documents, starting with alveolar consonants like の (no), な (na), す (su), し (shi), て (te) etc.^[1]

Yamada (1913) proposed that it is cognate with Old Korean 叱 (-s) (whence Middle Korean ㅅ (-s)). ^[2] However, the phonology does not match, and there is a distinct vestigial medial -s- that appears in certain ancient Japanese terms, such as 春雨 (harusame, possibly haru ("spring") + -s- (genitive) + ame ("rain")), 新稲 (nīshine, possibly nī ("new") + -s- (genitive) + ine ("rice")), 真青 (masao, possibly ma ("true, real") + -s- (genitive) + ao ("blue")).

つ • (tsu) 

1. (archaic, obsolete) genitive or possessive marker

   天(あま)つ風(かぜ)

   ama tsu kaze

   wind blowing from the heavens

   国(くに)つ神(かみ)

A few terms in modern Japanese have been derived from the possessive marker tsu:

• 目(ま) (ma, “eye”, combining form) + つ (tsu) + 毛(け) (ke, “hair”) → 睫(まつげ) (matsuge, “eyelashes”)
• 身(み) (mi, “body”) + つ (tsu) + 柄(から) (kara, “design → by itself”) → 自(みずか)ら (mizukara, “personally, oneself”)

• の (no)
