== incorrect ascription of origin of term == 

 This article mentions Cantonese as the source of some of the Kinship terms. That is incorrect. The source is Hokkien. The term kuya is from Hokkien kuya (姑爺), and was originally used by in-laws to call their son-in-law.  

 It would also be good if the page explained that kapatid, kapatid na lalake, etc. are dervied and not basic terms. The root and affixes could be explained.
