The aircraft was usually referred to by the British as simply "Concorde".[308] In France it was known as "le Concorde" due to "le", the definite article,[309] used in French grammar to introduce the name of a ship or aircraft,[310] and the capital being used to distinguish a proper name from a common noun of the same spelling.[309][311] In French, the common noun concorde means "agreement, harmony, or peace". [N 8] Concorde's pilots and British Airways in official publications often refer to Concorde both in the singular and plural as "she" or "her".[313][N 9]
