It’s not always so easy though. Here’s the results for the hashtag “teach.”
Do these pictures look like teach to you?
They don’t to me?
So what’s missing?
Figuring that out can really help me improve my understanding of what “teach” really means.
Remember there are at least three dimensions to the meaning of a word: dictionary, symbol, association.
The other place to look for visual meaning is in icons.  Icons look for the essence of a word, the thing that for me is missing
in #teach.
What do you think teach means? 
Can you take a picture of teach and post it to Instagram?
Tag me in the photo BELIEVE_ENGLISH, or use this hashtag #bengteach
