“Post-positioned adjectives” is actually a short-cut because, as the instructional material indicates, most cases can be explained as ellipsed clauses based on an S/V/PN pattern. For students who can understand appositives, this construction should be very easy to master, and it is also important for statistical stylistic studies because it has the effect of tightening the style by eliminating the pronoun and form of the verb “to be” that appear is subordinate S/V/PA clauses. Some writers use this construction frequently; others don’t. 

Suggested Directions for Analytical Exercises
1. Place parentheses ( ) around each prepositional phrase.
2. Underline verbs twice, their subjects once, and label complements (“PA,” “PN,” “IO,” or “DO”).
3. Place brackets [ ] around each subordinate clause. If the clause functions as a noun, label its function. If it functions as an adjective or adverb, draw an arrow from the opening bracket to the word that the clause modifies.
4. Place a vertical line after each main clause.
5. Label each post-positioned adjective "PPA."

Probable Time Required
     For students who have mastered clauses, two exercises should suffice.
