abstract/collective -yō(tl) — may be added to a possessed noun to indicate that it is a part of its possessor, rather than just being owned by it. For example, both nonac and nonacayo (possessed forms of nacatl) mean "my meat", but nonac may refer to meat that one has to eat, while nonacayo refers to the flesh that makes up one's body. This is known as inalienable, integral or organic possession. Derivational morphology -tia derives from noun X a verb with an approximate meaning of "to provide with X " or "to become X." -huia derives from noun X a verb with an approximate meaning of "to use X " or "to provide with X." -yōtl derives from a noun X a noun with an abstract meaning of "X-hood or X-ness." -yoh derives from a noun X a noun with a meaning of "thing full of X" or "thing with a lot of X." Verbs All verbs are marked with prefixes in order to agree with the person of the subject, and, where there is one, the object. In addition, verbs take a special suffix to mark plural subjects (only animates take plural agreement). An example of an intransitive verb, with subject marking: niyōli 'I live,' tiyōli 'you (singular) live,' yōli he, she, it lives,' tiyōlih 'we live,' anyōlih 'you (plural) live,' yōlih 'they live.' Subject and object marking The person prefixes are identical for all tenses and moods (with the exception of the imperative, whose prefix is x(i)-), but the plural number suffix varies according to tense or mood. In the table below, Ø- indicates there is no prefix. Note that prefix ti- means 'you (singular)' with no number suffix on the verb, but ti- plus the plural suffix (in the present -h) means 'we'. The imperative prefixes can only be used in the second person; for other persons, use the optative mood. As mentioned previously, verbal subject prefixes can also be used with nouns, to create a nominal predicate: nicihuātl 'I am a woman,' toquichtli 'you are a man,' 'nimēxicah 'we are Mexica.' Transitive and bitransitive verbs take a distinct set of prefixes (after the subject marking, but before the stem), to mark the object: The object always must be marked on a transitive verb. If the object is unknown or is simply 'things/people in general' the unspecified object prefixes may be used. Compare niccua 'I am eating
