What is the Greek word for fifteen fingers or toes?

There is no specific Greek word for "fifteen fingers or toes". However, you could express this concept in a few ways:

* Δεκαπέντε δάχτυλα/δάκτυλα των ποδιών (deka-pente dáktyla/dáktyla ton podιón) - This literally translates to "fifteen fingers/toes".

* Δεκαπέντε άκρα (deka-pente ákra) - This means "fifteen extremities", referring to fingers and toes as the ends of limbs.

* Πεντεδάκτυλος με δεκαπέντε δάχτυλα (pente-dáktýlos me deka-pente dáktyla) - This translates to "five-fingered with fifteen fingers", which could be used playfully or to emphasize the unusual number.

It's important to note that the concept of having fifteen fingers or toes is not common in Greek culture, so there might not be a single word for it.
