Perfective and Imperfective Aspect are marked by way of suffixes on the verb, hence immediately following the verb. Tense and mood are marked by way of preverbal particles. Very occasional use of adverbials alwes 'always' (a loan from Guyanese Creole English) and noiti 'never' in a position between the preverbal tense marker and the verbal complex suggests separability, hence I have included the option "in a leftward position". But it should be noted that cases of this kind are attested only in the speech of one person. In the speech of others, alwes takes a more peripheral position, and while noiti is attested in a preverbal position for several speakers, I have no examples where it cooccurs with preverbal markers.
