Teaching Notes.

Item 1. This table contains some analyses that may raise questions: The base naught in naughtier is from an obsolete noun that meant “Wickedness, evil, moral wrong, mischief.” Escapist contains a rare assimilation of ex-that occurs in a few adoptions from French and Italian: e\cancel{x} + s + cap\cancel{e} + ist Some students may want to analyze the base portune into port + une. There's something to be said for such an analysis: Compare the words like fortune, tribune, jejune, in which <une> looks and feels like a suffix. But apparently the <une> in opportune is better treated as part of the base rather than as a suffix. The suffix -ual in individual may seem odd to the students: It is a form of the more common -al, which forms adjectives and nouns.

Item 3. Other words with final <e> deletion: opportunist, simplest. Other words with prefixes or suffixes not listed in the tables: typists, friendlier, frightens, naughtier, affection, subtracting, informers, invisible, oppressive, escapist, vaporized, lovelier, lengthening, pointlessness, unassisted, suggests, individualize, moistened.
