Ancient Greeks did not say "dekatetra" for 14, i.e. ten-four, but as it is correctly written in TFA, they said "tetrakaideka" for 14, i.e. "four-and-ten", which is actually close to English "fourteen".

For example, already Aristotle used "dipoda" (2-feet) for humans and birds, "tetrapoda" (4-feet) for other terrestrial vertebrates and "hexapoda" (6-feet) for insects. After the same model one can say "oktopoda" (8-feet) about spiders and "tetrakaidekapoda" (14-feet) about woodlice.

Apologies - Ancient Greek!
