No, the dual number (if you mean that) was used in ancient Greek, but it doesn't exist in modern Greek. "Παντελόνι" is a noun in singular number. :-)
I think it had died out by Koine times already -- you'd need very ancient Greek to get a time when it was still alive.
But I have a soft spot for the dual number as well.
This was presented to me when doing part two of the "questions" category...dunno why it's there. Probably a bug. I'm on the web version.
"Pocket" in bulgarian is pronounced as "job". I clearly see the connection between the greek and bulgarian word. I just don't know if it was introduced in the language from Greek or Turkish. Does anyone know?
The Greek word came from Turkish ceb or cep.
I don't know about the Bulgarian but if I had to guess, I think Turkish is a more likely source than Greek.
"pants" is always plural in English, so you have to use the verb form "don't" instead of "doesn't".
"pants" is plural in English, so it has to be "The pants do not have pockets".
