Here's a breakdown of the words:
* 好き (suki) means "like"
* だ (da) is a grammatical particle used for making statements
* よ (yo) is a particle that adds emphasis and can be used to make the statement sound more assertive or friendly, depending on the context.
It's important to note that "sukidayo" is a more casual way to express liking. It's typically used between friends, family members, or close romantic partners. In more formal settings, you would use a more polite phrase like "suki desu" (好きです).
