Yahgan possesses a large number of adjective roots, especially those referring to physical states of matter, health, psychological states, etc. Many do double duty as nouns, adverbs, less often without derivation as verbs. Nouns and adjectives can be verbalized by adding -Vna '(be) in a state', or -ata 'become' or both -Vnata 'develop into a state' (where the identity of V is influenced by the final vowel of the root, but is often not identical to it). Such verbalizations are exceedingly common in the dictionary, and can be further derived and inflected.
