 The prefixes "naga-" and "maga-" may be shortened to "ga-" in colloquial speech and in colloquial writing, which may indicate a lack of aspect but it still preserves the form.Some argue that the difference between "nag-" and "mag-" versus "naga-" and "maga-" are either in formality ("naga-" and "maga-" being more formal) or in tense ("naga-" being more in the present and "nag-" being more in the past, while "maga-" and "mag-" are interchangeable).The prefixes "naka-" and "maka-" may be shortened to "ka-" in colloquial speech and in colloquial writing, which may get rid of the aspect within the prefixes.
