Excambie is a somewhat rare Scottish word that means "exchange" or "barter." The spelling of this word may appear unusual to many readers, but it adheres quite closely to the rules of English phonetics. The first syllable is pronounced "ek-" as in "echo," while the second syllable is pronounced with a short "a" sound, like "am" or "act." The final syllable, "-bie," is pronounced with a long "e" sound, like "bee." Altogether, the word is pronounced "ek-SAM-bee."
