nag-

• naga- — formal, literary
• ga-

Compare mag-, the actor trigger prefix, and -in-, which marks the complete aspect of most verbal triggers.

nag- (contemplative maga-, mag-, imperative pag-)

1. inchoative aspect of mag-; signifies that the action has started, whether or not it has been completed or still in progress

   Nagluto ko og utan ― I have/had cooked vegetables

   Nagluto ko og utan ― I am/was cooking vegetables

• Some argue that the difference between the forms nag- and naga- is that of aspect and not formality, where the former is to be used as the complete aspect, and the latter as the progressive aspect. Most grammatical literature, however, does not support such aspectual distinctions, referring to these forms as variants of one another. ^{[1] [2]} This goes in line with the practical use of the prefixes.
