Conjugations are like the "lifeline" of Tagalog grammar and you can have 1,001 ways to conjugate a single root word. You could also literally build new vocabularies by simply conjugating. For example, luto means cook but depending on how you conjugate it, words for utensils (pangluto/pinangluto), kitchen (lutuan), can be "created".
Learning the Tagalog verb system takes a lot of patience and expose yourself so you can get a "feel" of the language. Most Filipinos who speak Tagalog usually conjugate by how it "feels", this is why most Filipinos have a hard time explaining the grammar unless they have formal training in the Tagalog grammar
Pay attention to the pronounciations. Many words are spelled the same, but can have slightly different pronounciation and that changes the entire meaning of the word.

Or say malaki ang susó because if you say malaki ang súso, you will marked as a pervert. Haha
