From birdsite user railroadchuffs. Apparently, Sara Duterte's 10-million-peso children's book didn't even go through proofreading. #Philippines #Filipino
To clarify, "salu-salo" is not an acceptable word in #Filipino. The root word is "salo", and according to Filipino grammar rules, this is to be used as a verb or an adjective. In this context, the word is used as a noun, so the hyphen should be dropped, hence the correct usage "salusalo".
Also, as recent as 2014, rules around repeating words in #Filipino has changed. Although "pagsasalu-salo" is still acceptable, it is now preferred to not change the final "o" into a "u" when repeating words that end with "o". The rendering "pagsasalo-salo" is now more preferred.
