Most people notice that the meaning of the word “milk” fades after they have repeated it for a while. The word “milk” becomes a nonsense sound that no longer brings forth vivid sensory impressions of the white, wet, and cool liquid you know as milk. Did you notice that the word “milk” began to sound odd, like any other odd sound: baabaabaa or saasaasaa? This rarely happens in a conversation, when the sounds are words with particular meanings.
