To parse a word in a sentence:

Tell the part of speech.
Tell its properties.
Point out its relation to other words and give the rule for its construction.

To parse nouns:

Indicate that it is a noun and tell why it is a noun.
Indicate whether it is a common or a proper noun and tell why.
Indicate whether it is in the first, the second, or the third person and tell why.
Indicate whether it is singular or plural in number and tell why.
Optionally, indicate whether its gender is masculine, feminine, or neuter and why.
Indicate whether its case is nominative, possessive, or objective case and why.

Note:
A student thoroughly drilled in the Introduction may be able to introduce this third element of parsing, if the teacher chooses. The Rules of Syntax will, of course, be anticipated if applied here. The teacher can omit or use the rules, as he or she may think best.
