An interpretation is an <em>opinion or explanation</em> of the meaning of something. An Aesthetic interpretation is an explanation of the meaning of a work of art. When (A) A photograph is transformed into a painting; (B) A television show starts a new season and (D) A book is adapted into a movie, all have the same purpose, to show and <em>present the original in a </em><em>new and different way</em>. But a painting that was reproduced in form of a puzzle is still the same painting that was just cut into small pieces.
I believe that “chat” is stressed/accented and “el” is unstressed. Similar to the word “present,” where emphasis/accent is placed on “pres.” Hope this helps!
