Medium:

materials

Context:
The circumstances surrounding a text (anything from a book to
a statement). We gain clarity in determining a text from the
context.
Context can include:
the time and place in which a text is created/spoken/etc.
the background/biography of the author
the complete statement/text from which something is taken
(Narasingha Deva as example)

Without context, words and ideas can be twisted to mean
anything. With context, we get a better understanding of what
a text really means.
