vaisseau

Vaisseau is a French masculine noun meaning a vessel or ship. In everyday language it refers to a large craft that moves through water, such as a warship or merchant ship. The term is also used in modern contexts to describe spacecraft, with the widely used compound vaisseau spatial for outer-space vessels. In anatomy, vaisseau appears in phrases like vaisseau sanguin to mean a blood vessel.

Etymology and form: the word derives from Old French vaisse, vaisse, which itself comes from Latin vas, vasis meaning vessel or container. The modern form vaisseau is protected by standard French spelling, including the plural vaisseaux.

Usage notes: vaisseau is common in historical and literary descriptions of naval forces, as in vaisseau de guerre or vaisseau marchand. In contemporary science fiction or space-related discourse, vaisseau spatial is the standard term for a spaceship. The word is also found in medical and biological writing through its use in compounds describing bodily vessels.

Notable use: Le Vaisseau is the name of a science center in France, located near Strasbourg, focused on interactive exhibits and educational programs for children and families. As a proper noun, it preserves the ordinary meaning of the word while serving as a contemporary institution name.
