mmh.... some words are shortened using these marks
Bakit [ why ] - Ba't
some words have accent marks to differentiate the meaning of the same word
in short the same word has 2 meanings
Aso[ dog ] [ ah- so]
Aso [ smoke] [ ah- so] saying the syllable "so" is bit fast comparing with the first word
and sometimes the purpose of these marks is to tell you where should you put stress on a certain word.
be careful when you see these marks.
the first reply is useful * thumbs up*
