Here's a breakdown of the different ways "familiarize" can be used:
* To make someone familiar with something: This can be done by explaining, teaching, or providing experience with the subject. For example: "The training session aims to familiarize employees with the new software."
* To make something familiar to someone: This can involve repetition, exposure, or practice. For example: "The constant repetition of the new word helped me familiarize myself with its pronunciation."
Essentially, "familiarize" means to bring something from a state of unfamiliarity to a state of understanding and comfort.
