What is the difference between the words ‘this’ and ‘that’?


assistant
The difference between ‘this’ and ‘that’ has to do with proximity.  When referring to something that is in close proximity you would use the word ‘this’: “This finger hurts me the most.”  Conversely, if something far away you would use the word that: “That hill off in the distance is called the Blue Hills.”
