“Dalhin” is from the root word “dala” (bring). The infinitive/imperative of “dala” may be formed using the prefix “mag” (actor focused) or the suffix “in/hin” (object focused), but in the case of the latter, the form becomes irregular. It becomes “dalhin” instead of what would conform to the standard as “dalahin”. “Magdala ka ng libro” = Bring a book. “Dalhin mo ang libro” = Bring the book. Its conjugation is also affected in the future tense. Compare it with the conjugation of “basa” (read) that follows the standard format. Basahin (to read) – binasa (read); binabasa (reading); babasahin (will read) Dalhin (to bring) – dinala (brought); dinadala (bringing); dadalhin (will bring) “Ano ang puwede kong basahin?” = What can I read? “Ano ang puwede kong dalhin?” = What can I bring?
