Answer:
Analogy is a similarity between things that are not intrinsically similar. It is used when one wants to make a point. An example of an analogy is the following one:
Kiko Loureiro, Megadeth's lead guitarrist, explained on a recent video why he did not keep in touch with the members of Angra's original line-up right after they departed and Angra recorded a new album with three new members (Angra was Kiko's previous band). Kiko used an analogy:
"I did not keep in touch with them because I did not want the new guys to feel insecure. It is the same when you start a new relationship: if you keep in touch with your ex-girlfriend, the current one will feel insecure, and she will probably leave you."
