An analogy, by definition, is <span>a comparison between two things, typically on the basis of their structure and for the purpose of explanation or clarification.
There are some websites that can help with them, here is one that explains a basic analogy: https://www.teachervision.com/vocabulary/reading-comprehension/6697.html
An example of an analogy is: If TURTLE is to SLOW, then CHEETA is to _____
By background knowledge, we know that Turtles are Slow. So the animal is being compared to its speed. Cheetahs are known to be fast, so the word FAST fits in with the analogy. It's comparing the Cheeta to its speed, as well as being the opposite of the Turtle's speed.
Analogies are not always opposite, but common examples are opposite analogies. A non-opposite example would be:
Triangle is to THREE as Square is to FOUR
This is comparing the sides of the figures. Hopefully this helps.</span>
