פירוש על ברכות 112:6

A district in Asia Minor.

In this version, the name is regarded as a combination of the Aramaic Kofa "a beam," and the Greek δέκα "ten." But there is another version in the Palestinian Talmud, Ma'aser Sheni, iv. 55b, where it is considered to be made up of κάππα "twenty" and δόκοι "beams." See Krauss, p. 559.
