To see an event and be able to describe it and confirm that it happened. English = eyewitness, witness. 2. To see or notice someting, in the past. English = (have) seen, saw. Augmented Meaning: 1. Auslan verb signs usually do not change to show time (i.e. past, present and future tense). However, there are a few exceptions, almost all of them made by joining the verb sign with a sign derived from one of two signs meaning 'finish'. The two signs are made like a single sign and often the overall meaning of the sign can change, as in this example.
