Aspect Prefixes — Mo, Mag, Na, Nag
The four prefixes that drive most Cebuano verbs
Overview
Examples & Usage
Mokaon ko ugma.
I'll eat tomorrow.
Mo- = future / contemplated.
Magtrabaho ko karon.
I'll work now / I'm about to work.
Mag- = durative; the action is starting.
Nakaon na ko.
I have eaten.
Na- = completed.
Nagkaon ko.
I'm eating (right now).
Nag- = ongoing.
Nasuko ko nimo.
I got angry at you.
Na- + emotion root = experienced state.
Nagguol ko karon.
I'm sad now.
Nag- + emotion = ongoing state.
Key Tips
- 1Mo- is the safe default for future actions: Mokaon ko, Moadto ko, Mopalit ko.
- 2Nag- and na- look similar but mean different things — nag- is happening now, na- is already done.
- 3For emotions, na- and nag- are both common: Nasuko vs Nagsuko (both correct, slightly different aspect).
- 4Listening for the prefix tells you the timeline of the action — Cebuanos rarely use other tense markers.
- 5Some roots take only certain prefixes (e.g., kaon takes mo-, mag-, na-, nag-, but not all roots are this flexible).

Frequently Asked Questions
What is the simplest rule for choosing mo-, nag-, or na-?
The simplest rule: Mo- = future (not yet started), Nag- = now (happening right now), Na- = done (already finished). 'Mokaon ko unya' (I'll eat later — mo-). 'Nagkaon ko karon' (I'm eating right now — nag-). 'Nakaon na ko' (I've already eaten — na-). This three-way distinction covers the vast majority of everyday verb use. Start here before diving into the subtleties.
When do I use 'mag-' versus 'mo-' for future actions?
'Mo-' marks a single, one-time future action with immediate intention: 'Mokaon ko unya' (I'll eat later). 'Mag-' emphasizes a planned or durative action — one that will be ongoing or habitual: 'Magtrabaho ko sa Biyernes' (I work/will work on Friday — ongoing plan). In practice, mo- is the safe everyday default. Mag- appears more with activities that span time: work, study, sleep, cooking.
Why do emotion words often use 'na-' prefix?
'Na-' marks completed entry into a state — the moment when something happened or was experienced. Emotions naturally fit this: 'Nasuko ko' (I got angry — I entered an angry state), 'Nalipay ko' (I became happy). This differs from 'nag-' which marks ongoing state: 'Nagsuko ko' (I am/was angry — ongoing). Both are correct and commonly used for emotions, with 'na-' emphasizing the entry/onset and 'nag-' the continuation.
What is the difference between 'na-' (prefix) and 'na' (the word 'already')?
These are different: 'Na-' as a verb prefix indicates completed aspect: 'Nakaon' (has eaten), 'Naabot' (has arrived). 'Na' as a separate particle/word means 'already': 'Nakaon na ko' (I have already eaten — na prefix on verb + na already). The standalone 'na' at the end of a sentence or phrase always means 'already/now' and is NOT part of the verb. Learning to distinguish these is important for parsing sentences correctly.
Do all Bisaya verbs take all four prefixes freely?
No — not all roots are equally flexible with all prefixes. Common high-frequency verbs (kaon, adto, trabaho, basa, luto) accept most prefixes. Some roots take only certain ones based on their meaning. Stative roots (exist, have) have limited aspectual variation. The safest approach is to learn the most common aspect forms of each high-frequency verb through exposure rather than trying to mechanically apply all prefixes to every root.
