Tónteel translates approximately to ‘water that is wide.’

It is the Navajo name for an ocean.

I’ll break the word down further. ‘Tó’ means ‘water’ and ‘nteel’ (pronounced “ntyehhl” with the “nt” part sounding like the end of “don’t”) means ‘it is wide.’ Both parts of the word are used widely across the Navajo language in conjunction with other words and descriptors to name similar things.
