Meaning: grass, or hay.

The word tł’oh generally refers to plantlife that have a grass-like appearance. For example, the Navajo word for onion references grass – mainly because of the stalks that grow above ground.

You may hear that tł’oh is expensive nowadays; that would be in regards to bales of hay (for livestock use), the price for which has risen considerably in the past few decades in and around the reservation.
