The word itself is short for modulator-demodulator. A modem is a device that modulates (To vary the frequency, amplitude, phase, or other characteristic of electromagnetic waves) an analog signal to encode digital information. It also can take in an analog signal and decode the digital information from it (demodulates).

In simpler terms, a modem is the box (usually provided by your internet Service Provider (ISP)) that tipically sits between the in the wall and either a wireless router or your computer.

Its purpose is to translate the digital signals that your computer sends out into an electronic signal that can easily transmitted and decoded by another modem at the message's destination and vise versa.
