What does one call words or phrases that cannot be or rarely refered to with kanji


I have found that many words are only used in hiragana and because of this i
can't seem to find a good way to learn them as i am studying words that use
kanji due to the site i am using. Like-ごめんなさい, そうか, etc. are these type of
words given a type of name?




To my knowledge, there is no term that specifically means "word usually
written in kana". In modern standard Japanese, Western-origin loanwords are
almost always written in katakana. Particles, adverbs and interjections tend
to be written in hiragana. Learning words based only on kanji may not be a
good idea because of this.
