Aspect Prefixes — Mo, Mag, Na, Nag
The four prefixes that drive most Cebuano verbs
Overview
Cebuano verbs don't conjugate by tense the way English does. They conjugate by aspect — whether an action is completed, ongoing, future, or habitual. Four prefixes do most of the work. The four core aspect prefixes: • Mo- — future / contemplated action. Mokaon ko ugma. (I'll eat tomorrow.) • Mag- — durative / continuous action. Magkaon ko karon. (I'll be eating now / I'm about to eat.) • Na- — completed / realized state. Nakaon na ko. (I have eaten.) / Nasuko ko. (I got angry.) • Nag- — ongoing action / state. Nagkaon ko. (I'm eating right now.) / Nagguol ko. (I'm sad.) How to read them: • Mo + root = future intention. The most common future-tense form. • Mag + root = durative; emphasizes the action will continue or is about to start. • Na + root = completed; the subject has experienced or completed something. • Nag + root = currently ongoing. Many emotion words use na- or nag- because emotions are states: • Nasuko ko — I got angry (completed entry into angry state) • Nagguol ko — I am sad (ongoing state) • Naulaw ko — I got embarrassed (completed state) Verbs can take other prefixes too (gi-, gika-, mi-, etc.) — but mo-, mag-, na-, and nag- handle 70% of daily speech.
Examples
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.
💡 Tips to Remember
- •Mo- is the safe default for future actions: Mokaon ko, Moadto ko, Mopalit ko.
- •Nag- and na- look similar but mean different things — nag- is happening now, na- is already done.
- •For emotions, na- and nag- are both common: Nasuko vs Nagsuko (both correct, slightly different aspect).
- •Listening for the prefix tells you the timeline of the action — Cebuanos rarely use other tense markers.
- •Some roots take only certain prefixes (e.g., kaon takes mo-, mag-, na-, nag-, but not all roots are this flexible).
