Notes
GENERAL INFO
Grand is an adjective meaning "big," "tall," or "large." It can also mean "great" or "important" depending on context.
USAGE
It usually precedes the noun. For example, "un grand arbre" (a tall tree) or "une grande ville" (a big city). It describes physical size, but also metaphorical scale.
TRAPS
Grand agrees in gender and number: *grand* (m.s.), *grande* (f.s.), *grands* (m.pl.), *grandes* (f.pl.).
Its placement can subtly change meaning: "un grand homme" (a great man) vs. "un homme grand" (a tall man).
With liaisons before vowels or mute h, the final 'd' will sound like 't' ("grand‿homme" /gʁɑ̃t‿ɔm/)
