Hi GypsyDavey. Learning French has shown me how little I know of my own (English) language, especially grammar. So I've been studying it in order to progress with my French. I understood a Predicate required a verb, otherwise it was an adjective. Am I mistaken? I'm still not much good at this. Thanks.

@ Lo. In French most adjectives must agree with the gender and number of the noun they modify.There are always exceptions. Petit modifies a singular masculine noun. Petits modifies a plural masculine noun. Petite modifies a singular feminine noun and Petites modifies a plural feminine noun.
There is not a one-size-fits-all rule about adjective placement. Most adjectives are placed after the noun they modify. Some are always placed before (the BAGS rule). http://french.about.com/od/grammar/a/adjectives_4.htm And some might go either before or after but they have a different meaning depending on placement (before the noun, they are subjective; after the noun, they are objective).
