Can you see the red flag over there?
I can't help thinking about how others think of me.
The sun was so bright, I could barely see how high the balloon had risen.
This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means see, and the える (with the え in there) suggests that this is "potential" form. So, instead of just being "to see" this word means can see or just plain old visible.
The reading for this word is the same as the one you learned with the kanji (the kun'yomi reading). So as long as you know that you should be able to read this word as well.
