Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means present time, but you can't "to present time." If you try to do present time, the best you can do is try to show it. Kind of a weird connection, but if you think through it a couple times it might get better.
Do you remember learning 現れる? This has the same exact pronunciation!
I knew that she would show her true colors in the end.
