naisip

Na isip is a Filipino verb form derived from the root isip, which means to think or to consider. The prefix na- indicates a completed action, so naisip denotes that thinking has already occurred. It is used to express that someone has thought of something or formed a thought in the past.

Common examples illustrate its use: naisip ko ang sagot (I thought of the answer), naisip niya ang plano (he/she thought of the plan), and naisip nila ang posibilidad (they thought of the possibility). In these sentences, naisip anchors the thought to a past time frame and to a specific subject.

Relation to other Filipino verb forms is notable. Iniisip is the present tense form meaning “is thinking” or “is thinking about.” Naiisip is another present-related form used to express that something comes to mind or is being thought of. These related forms show how the same root is adapted for different tenses and aspects.

Usage and nuance. Naisip is common in both spoken and written Filipino and is often used in narration, reporting, or everyday conversation to indicate that a mental act occurred before the moment of speaking. It can pair with various objects—the thing thought about can be a problem, plan, idea, or possibility—without requiring a specific direct object marker beyond the pronoun subject.
