language
"Language" is a rich and important word in English. It has a few closely related but distinct meanings — from the system humans use to communicate, to the specific way someone speaks or writes, to the words used in a particular field. Here are the most common senses.
This is the most fundamental meaning. Language is the system of words, sounds, and grammar that humans use to communicate with each other. Think of it as the 'tool' that allows people to share thoughts, feelings, and ideas. Every human society has one.
