About words with accent marks?

we don't offenly used those accent marks or what we called "mga tuldik" i think most of filipino doesn't know about it.^^
anyway about those marks

´ Pahilís (Acute)
` Paiwà (Grave)
ˆ Pakupyâ (Circumflex)
it refers on how we pronounce each words correctly because some filipino words has a double meaning. it is usually written in filipino dictionaries and is written right above the Vowel Only.

for instance: the word " HAPON"
hápon (afternoon) more like longer pronunciation of "ha" haaapon.
Hapón (japanese) emphasizing the letter "O" short pronounce hapOn.

" ^ " a combination of the pahilís and the paiwà marks.
BASA
basa (to read) no accent mark or malumi
basâ (wet)

i addition ba't is not one of these.. its a short term for "bakit"
when you saw a filipino words with mark like this " ＇" it means to be shorten. counterpart in english "it's" it is. "doesn't" does not. etc.
