Koidiku (Koidik)

Sun-up, dawn, daybreak, cockcrow.

Köie (Köis)

Rope, cable. After the former rope-making community of Köismäe.

Kõivu (Kõiv)

Alternative, dialectal and/or Võro* term for Kase (cf. koivu in Finnish, kõuv in Livonian, and koiv in Veps). Counterpart in antiquity to Lõhmuse. Variants include arukõiv (see Arukaskede); marokõiv (see Kase [above]), and sookõiv (see Sookaskede). Tree/shrub group, see Leedri.

* Strictly, Võru, but the ‑o ending is proper to the Võro language/dialect, and was also proposed by Hurt (see Oti) as part of the Estonian language reform (see also Aate) to replace the ‑u ending, but it didn’t catch on.
