A bunch of the affixes start out as infixes (-um-) or postfixes that become infixes (-in) / (-an)...as opposed to MA- / MAG- and other prefixes
MAmatay - natural death; MAGmatay - extinguish lights/aircon/TV/etc
pINatay; pINapatay; papatayIN - murder
pUMatay; pUMapatay; papatay - kill more generally
Of course the structure of them fit seamlessly into the consonant(s) - vowel chunks. Just so your thinking of the "more fun" in the Philippines that waits in the affixes.
