Tagalog's um-um paradigm for conjugating the actor-focused form of verbs

In Tagalog, the um-um paradigm is used to conjugate the actor-focused form of verbs. This paradigm involves the insertion of the infix um before the first vowel in certain forms. For example, the actor-focused infinitive form of the verb bele, meaning to buy, becomes boomy. Additionally, the incomplete form or progressive form of bele is boomy bele, where the first syllable of the stem is reduplicated before the infix um is inserted. This highlights the importance of considering the order of affixes and reduplication in creating the final form of verbs with infixes.
