appeal, sue, complain
訴える（うったえる）、訴訟（そしょう）、告訴（こくそ）
to appeal/sue, lawsuit, prosecution
On-reading (ソ) is used in compounds; kun-reading (うった(える)) is used standalone or with okurigana. Appears in many compounds — memorize the key ones rather than the kanji in isolation. Has multiple meanings (appeal; sue; complain). Context determines which applies — pay attention in reading passages. This kanji forms verbs/adjectives with okurigana. Practice both the word form and compound forms.
