Slash(/)
The slash (also known as the diagonal or slant, or more esoterically
as the solidus, virgule or shilling) is a somewhat nebulous mark.
There are a couple of situations where no other punctuation will
do, but often it is used as a casual shorthand for more precise modes
of expression. Since it runs the risk of being ambiguous, it should
be applied with caution. In more formal genres of writing, such as that
expected for academic journals, it may be considered too informal or
imprecise to be used at all.
The functions of the slash are as follows:
• Indicating "and" or "or" relationships
• Indicating various other relationships between words or
numbers
• Separating lines of poetry
INDICATING "AND" OR "OR" RELATIONSHIPS
The slash may be variously used to indicate options, dual roles and
alternatives.
• As a symbol for and, it may be used to identify an entity that
has more than one characterization or function.

baby-sitter.

(Note that if you were vocalizing such sentences you would say,
"vice-president of finances slash baby-sitter" and "trial slash media
