is is true

[jay90]

is it true that the word myth is derived from the latin for moth meaning lying mouth?

[Clanad]

According to Encyclopedia Mythica, the word myth comes from the Greek "mythos" which originally meant "speech" or "discourse" but which later came to mean "fable" or "legend"...

And as for the Latin word for moth, I don't know what it is, but it probably doesn't sound anything like moth or myth or mouth.

The English word Moth comes from the Anglo Saxon which sounds about the same.

'Blatta' and 'tinea' were words used to mean 'moth' in Latin. If you click here Jay, you will be taken to the Yourdictionary website. Add it to your 'Favourites' list and - whenever you need to establish a word's etymology - all you have to do is put it into the slot and click 'Go'. Try it with 'myth'. Cheers

oh, both blatta and tinea have modern Latin meanings.

Blatta Blatta is a beetle - I think you can see why, family Blattidae, zillions of genera

Tinea - ringworm

Quite, PP, but the Oxford Latin Dictionary - in the English > Latin section - offers...moth = blatta, tinea. In the Latin > English section, it offers blatta = cockroach, moth and tinea = grub, maggot.
Seems pretty clear that most creepy-crawlies were much the same as far as the Romans were concerned!
