In Gurindji Kriol, tense markers are Kriol-derived free morphemes which precede the verb or are clitics attached to subject pronouns. Aspect markers are Kriol -bat (transitive verbs), -in (intransitive verbs) and Gurindji-derived -karra (general) verbal suffixes. Note that these are continuative markers rather than im/perfective markers.
