Placement of Adjectives
Descriptive adjectives (in French adjectifs qualificatifs) normally go after the noun they modify (unless they are the short list of short adjectives that go in front). But what if there are two such adjectives; what do you do then? What if there are more than two??? And what if an adjective turns up where it doesn’t belong?
French-English Correspondences
How French and English word-endings that are similar are nonetheless different. That is, how to get easily from an English form to a related French form, and vice versa.
Genders
Take advantage of the fact that some French noun endings are gender-specific. Learn these and remember them, “jusqu’au jour de votre mort!”
