The two suffixes of Type 5 have nothing much to do with each other except for both being Type 5. As a result, no verb occurs with both of these suffixes at the same time.

-lu' indefinite subject

This suffix is used to indicate that the subject is unknown, indefinite, and/or general. Since the subject is always the same (that is, it is always unstated), the pronominal prefixes (section 4.1.1) are used in a different way. Those prefixes which normally indicate first- or second-person subject and third-person singular object (vI-, Da-, wI-, bo-) are used to indicate first- or second-person object. Thus, vI-, which normally means I do something to him/her, when in a verb with -lu' means someone/something does something to me. Similarly, the prefix lu-, which normally means they do something to him/her, becomes someone/something does something to them.

Daqawlu' someone/something remembers you (qaw remember)

wIleghlu' someone/something sees us (legh see)

Soplu' someone/something eats it (Sop eat)

Verbs with -lu' are often translated into the English passive voice.

Daqawlu' you are remembered

wIleghlu' we are seen

Soplu' it is eaten

When used with the verb tu' find, observe and a third- person singular subject pronoun (0), the resulting verb form tu'lu' someone/something finds it is often translated by En- glish there is.

naDev puqpu' tu'lu' there are children around here, someone/something finds children here (naDev hereabouts, puqpu' children)

See section 3.2.2 for more information on how this suffix interacts with the -wI' suffix. 

Multiple uses of -lu' in a complex sentence refer back to the same indefinite subject. 

Heghlu'DI' mobbe'lu'chugh QaQqu' Hegh wanI' When someone dies, if (that same) someone is not alone the death event is very good 

-laH can, able

jIQonglaH I can sleep (Qong sleep)

choleghlaH you can see me (legh see)

nuQaw'laH he/she can destroy us (Qaw' destroy)
