Imagine you are reading an article, story or exam reading paper and the main character is walking home, watching their feet kicking the *____ as they walked, and listening to the sound it made. If we put *tightly packed snow, we would visualise white thick snow and the sound would be a crunching noise. But if we insert *slush we would visualise an almost grey, melting wet unpleasant snow and the watery sloshing sound. The overall effect would be different. Now we see that using a more defined word than snow can change our comprehension and if you don’t know those words you can miss a lot.
