Sing
"Sing" is a word that was used quite commonly in traditional Hiligaynon, but has mostly been replaced by the word "sang." Currently, its main use is to form adverbs. Here are a couple of its older uses, which you occasionally still see today.
Quantities
"She gave us three flowers." — "Naghatag siya sing tatlo ka bulak sa amon." (hatag = give, bulak = flower)
"The police were able to catch two criminals." — "Ang pulis nakadakop sing duha ka kriminal." (pulis = police, kriminal = criminal)
"We don't have any peanuts." — "Walâ kami sing mani." (mani = peanut)
Non-focus Indefinite Article: a/an, no article
In Action/Actor focus sentences, the object can be labeled with "sing."
"John threw a ball." — "Si John naghaboy sing bola." (haboy = throw, bola = ball)
"The goat ate an apple." — "Ang kanding nagkaon sing mansanas." (kanding = goat, kaon = eat, mansanas = apple)
also: "The goat ate an apple." — "Ang kanding nagkaon sing isa ka mansanas."
or: "The goat ate apples." — "Ang kanding nagkaon sing mga mansanas."
"They did evil." — "Naghimô sila sing malain." (himô = do/make, malain = bad/evil)
To make a definite article ("the") before the object in an Action/Actor focus sentence, the word "sang" is used.
"The goat ate the apple." — "Ang kanding nagkaon sang mansanas."
In modern times, "sang" can be used for both indefinite and definite articles.
