HI Valeugraph! There is indeed a difference between MAPA- and MAKA-. MAPA- generally means "to be able to be." Thus, in the song you mentioned, "Mapapantayan" means "to be (able to be) equalled." Usually it is just "MA-." It just becomes "MAPA-" since the main/root word is "pantay" which means "equal." There is this doubling of the "pa" syllable in "pantay" to indicate that the word "MAPAPANTAYAN" implies an ongoing attribute. So in the sentence, "Ang pagmamahál ng iná sa anák ay hindî mapápantayán." the phrase "ay hindi mapapantayan" indicates an ongoing attribute or an adjectival phrase to describe the love of a mother. In some cases, you may find it just "MAPANTAYAN" which means "to match or to equal" like in the sentence : "Ang nais ko ay mapantayan siya." (What I want is to equal/match him.") MAKA- on the other hand indicates a quality/attribute. It is usually added before a noun to create an adjective describing a subject. E.g. "Maka" + "bayan" >> "Makabayan" which means patriotic ("bayan" means country/nation). "Maka" may also be added before a verb to indicate an "opportunity" or to mean also "to be able to" just like "MAPA" above. E.g. "Maka + tikim" >> "Makatikim" (to be able to taste), "Maka + kita" >> "Makakita" (to be able to see), "Maka + pantay" >> "Makapantay" (to match) ***My example above ("Mapantayan") can also be "Makapantay" but not "Makapantayan" as there is no such word. "Ang nais ko ay ang makapantay sa kanya." (What I want is to be equal with him)
