Today’s phrase is Navajo for “many” or “much” or “a lot.”
It’s used in reference to the quantity of something.
Take the following picture as an example:
Notice all the Navajo words in this picture! You can see the big truck (chidí tsoh) and it’s carrying a lot of hay (tł’oh), which happens to be alfalfa (tł’oh waa’í) and it’s early in the morning (abiní).
So here’s a sentence that demonstrates a simple usage:
Tł’oh waa’í t’óó ahayóí!
See! You’re learning Navajo!
