English etymology limitations
The given etymology really only suits the first definition, the one referring to light. But for the ones referring to cannulae or tubes, it seems insufficient. - 24.16.159.68 21:56, 22 September 2023 (UTC)


 * The etymon does have the sense of “an opening”, thus justifying the biological/medical senses.  ·~   dictátor · mundꟾ  22:19, 22 September 2023 (UTC)
