aux: auxiliary
In Uralic traditional grammars auxiliaries are not often discussed about comprehensively. It is recommended to use a closed set of verbs as auxiliaries, for example the main modal verbs as well as the auxiliaries used in periphrastic tense constructions, and the negation verb if any. The verbs selected should be documented in the language specific documents.
