 The "Stative Form" does not have a "Potential Mood".The "hi-" prefix before "gugma" is necessary for the verb to take in a direct object, so the "imperatibo examples" would imply a direct object.The "nagka-" and "magka-" prefixes are different from the "na-" and "ma-" in that they have the essence of a slowly but surely, or steady, change that is occurring within the topic.
