Assimilation (phonology)

language culture Maturity 11-13 Next article →

Have you ever noticed how words change when we speak fast? This is called assimilation. It happens when one sound changes to match a nearby sound. This makes speaking feel smoother and easier.

Sometimes, a sound changes to match the one coming next. We call this anticipatory change. In the word "handbag," the sounds change in quick speech. The sounds become more alike because they use the same part of the mouth. This happens in many languages. In Italian, some sounds changed over a long time to match others.

Other times, a sound changes to match the one before it. This is called lag change. In English, the word "it is" can become "it's." The sounds shift to help the words flow together.

Sometimes, two sounds join to make one new sound. This is called coalescence. For example, "don't you" can sound like "don't-chu." The two sounds fuse into one. This can happen in many ways. Some sounds get smaller after they join. Others stay the same but still show they have fused. These changes help our speech move along naturally.
