I worked on this short animation about the proper use of the words "rin" and "din" from the Filipino language for Knowledge Channel. These two words roughly translates to "as well" in English grammar. Most people use these in a mixed manner not knowing when they should be used and just say either of them randomly, when in fact "rin" should be used when a vowel precedes it and "din" is used when a consonant precedes it.
The difference between the Filipino grammar words of "rin" and "din"
