(Jōyō kanji)

• Go-on: た (ta)
• Kan-on: た (ta)
• Kan’yō-on: だ (da, Jōyō)
• Kun: つばき (tsubaki, 唾)、つば (tsuba, 唾, Jōyō)、つ (tsu, 唾)

Derived as the 連用形 (ren'yōkei, “continuative or stem form”) of now-obsolete verb 唾吐く (tsubaku, “to spit, to expectorate”), itself from 唾 (tsu, “saliva”) + 吐く (haku, “to expel from the mouth: to spit, to vomit, to exhale”).^[1][2]

• (Tokyo) つばき (Odaka – )^[1]
• IPA^(key):

Appears to be a shortening of tsubaki above. Alternatively, may be a fusion of tsu below with particle は (wa, originally pa in Old Japanese, combining in some cases as ba).^[2]

• (Tokyo) つば (Atamadaka – )^[1]
