In order to change the meaning of the word "teach" from "to give instruction" to "to give instruction with," you would add the prefix "co-."
Explanation:
Prefixes are added at the beginning of a word to modify its meaning. In this case, the prefix "co-" can be added to the word "teach" to indicate that the instruction is being given in collaboration or conjunction with someone else.
To demonstrate this, you would simply add the prefix "co-" in front of the word "teach," resulting in the new word "co-teach." This modified word would then convey the meaning of giving instruction together or with someone else.
Remember, adding prefixes or any other word modifications is a common way to change the meaning of words and expand our vocabulary!
