Don’t confuse this character with “look at” (看, Character 200 above).
Pronounced as zháo, this character can have a variety of meanings. “To catch” means “touch”, “come into contact with”, as in “catch a cold”. Pronounced as zhe, it is used after a verb to indicate an action in progress, hence our choice “-ing” for the meaning.
