Annotation of the verb sú

The verb sú in Nheengatu can function either as a full verb of physical motion or as an auxiliary expressing ingressive aspect. It should be annotated as AUX only when it marks the beginning or onset of an event expressed by the main verb (e.g., Ukanhemu usú umbawa uyutika wakutiwa kwera ‘They began to disappear’). In all other cases where sú denotes actual physical motion or direction toward a goal, it must be annotated as VERB (e.g., Ape yawaraté uyusikí usú merupí sesé ‘Then the jaguar went slowly over him’; Uyapí usú apekatú kití ‘[He] threw it far away’; Uyupiri usú uikú ‘She went rising up to the sky’). This distinction ensures that only sú with purely grammatical (aspectual) meaning is tagged as AUX.

Decision Table for Annotating sú

Context	Function of sú	Meaning Contribution	UD POS Tag	Example
sú expresses physical movement of the subject (e.g., going, coming, departing, moving toward a goal)	Main motion verb	Lexical (concrete motion)	VERB	Ape yawaraté uyusikí usú merupí sesé ‘Then the jaguar went slowly over him.’
sú combines with another motion verb to indicate directionality or continuation of movement	Main motion verb	Lexical (reinforces trajectory or direction)	VERB	Uyupiri usú uikú ‘She went rising up to the sky.’
sú precedes a stative or non-motion verb, marking the onset of the event (ingressive aspect)	Auxiliary	Grammatical (aspectual: beginning of event)	AUX	Ukanhemu usú umbawa uyutika wakutiwa kwera ‘They began to disappear.’
sú appears after a transitive verb denoting an action that causes an object to move toward a goal	Main motion verb	Lexical (motion of object)	VERB	Uyapí usú apekatú kití ‘[He] threw it far away.’
sú does not contribute to meaning of motion or inception (idiomatic or unclear cases)	Context-dependent	Requires semantic judgment	VERB or AUX (decide based on aspectual vs. lexical contribution)	—

Heuristic Summary

• If sú adds aspectual meaning (onset or beginning of the action) → tag as AUX.
• If sú contributes motion meaning (movement of subject or object) → tag as VERB.
• When in doubt, check whether sú could stand alone as a motion predicate (‘to go’). If yes, it is likely a VERB.
