kahibalo / kabalo

1. Forms and Regional Variants
The root word is hibalo (or balo). The word for 'know' changes based on formality and geography:

• Kahibalo: The formal, standard form used in writing.
• Kabalo: The dominant conversational form in Mindanao, but also widely used and perfectly understood in Cebu.
• Kaantigo: A standard Cebuano synonym widely used across regions, including Cebu, often used for skills.
• Kamao: The most common conversational synonym for 'know how' or skills in Cebu City.
• Kahibaw / Kabaw: Conversational forms widespread across Cebu and Bohol where the 'l' is dropped. Note: 'Kabaw' meaning 'know' is an informal eye-dialect used in texting or chatting. In formal writing, 'kabaw' means 'water buffalo' (carabao), while 'kahibalo' is used for 'know'.

2. Sentence Structure
It acts as an Actor-Focus (or Experiencer-Focus) predicate followed by the 'knower' (in the focused form like ako) and the 'knowledge' (marked by non-focused markers like sa or og). Factual knowledge is most frequently expressed as a full clause introduced by the linker nga (e.g., Kahibalo ko nga...).

3. Negation
To say you 'don't know,' the choice of negator depends on the type of knowledge:

• Facts vs. Skills: As a general grammatical guideline, use wala to negate information or facts (e.g., 'I don't know the name') and dili to negate skills or habits (e.g., 'I don't know how to drive'). However, conversational Cebuano is much more fluid, and native speakers frequently blur this line (e.g., Wala ko kabalo unsaon... or Dili ko kabalo kung...). In speech, these negators are almost always contracted to Wa ko kabalo and Di ko kabalo.
• In casual conversation, Ambot is used for 'I don't know' (lack of answer).

4. Knowing What, Where, Who, or How
You can express knowing what, where, who, or how by following the verb with a question word (e.g., Kahibalo ko unsaon pagluto or Kahibalo ko kinsa ang nidaog). Important Warning: While you can use kahibalo with question words for factual clauses, do not use it to mean knowing a person or a place. Use kaila for knowing or being acquainted with a person (e.g., Kaila ko ni John, not Kahibalo ko ni John) and katultol for knowing a location or route. For skills, the most common everyday way is to link kahibalo directly with a future/infinitive verb using mo- or mag- (e.g., Kahibalo ko molangoy - I know how to swim; Kahibalo ka magbinisaya? - Do you know how to speak Bisaya?).

5. Finding Out
While kahibalo is a state of being, adding the maka- prefix (makahibalo) changes the meaning to the act of discovering, learning, or happening to find out information. Its past-tense counterpart, nakahibalo, is used to say 'found out' or 'learned' (e.g., Nakahibalo ko nga... - I found out that...).
