Language Is Learned

As we just learned, the relationship between the symbols that make up our language and their referents is arbitrary, which means they have no meaning until we assign it to them. In order to effectively use a language system, we have to learn, over time, which symbols go with which referents, since we can’t just tell by looking at the symbol. Like me, you probably learned what the word apple meant by looking at the letters A-P-P-L-E and a picture of an apple and having a teacher or caregiver help you sound out the letters until you said the whole word. Over time, we associated that combination of letters with the picture of the red delicious apple and no longer had to sound each letter out. This is a deliberate process that may seem slow in the moment, but as we will see next, our ability to acquire language is actually quite astounding. We didn’t just learn individual words and their meanings, though; we also learned rules of grammar that help us put those words into meaningful sentences.
