To Indicate
To Show
transitive verb, godan verb
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means indicate so the verb vocab version is to indicate or to show. This isn't used for "showing" a physical thing, this is more like when "a study shows that ...."
しめす
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you:
Studies seem to indicate or to show that She-men (しめ) are way more powerful than He-men. Just look at how much bigger their swords and biceps are.
約束なんてしないで。言葉ではなく行いで示してよ。
Don’t promise me anything. Actions speak louder than words.
