Tagalog, like many other languages, has specific rules about how syllables and words can end. In Tagalog, words typically end with vowels (a, e, i, o, u) or consonants like "g", "k", "m", "ng", "p", "r", "s", "t", or "y".
There might be a few exceptions, like borrowed words from other languages that retain their original endings, but these are not common.
If you are looking for words that have "n" within them, then you can find a lot! Just tell me what kind of words you are interested in (nouns, verbs, adjectives, etc.), and I can give you some examples.
