katoa
1. (modifier) all, every, totally, wholly, completely, without exception - used to indicate that something is all-encompassing, all-consuming or all-conquering. Sometimes used after a verb, often preceding the noun it qualifies. Where katoa follows a verb in the passive it will take a passive ending also, usually -tia. In this situation the passive ending may be dropped from the verb, but not from katoa.
