What does dauphin mean?
A dauphin was the eldest son of the reigning king of France and thus the heir apparent to the throne. The title originated in the 14th century, deriving from the province of Dauphiné, which took its name from the dolphin emblem borne by its counts; when the region passed to the French crown, its ruler's title was reserved for the king's eldest son. From then until the French Revolution abolished it, every French monarch-in-waiting bore the designation, making figures such as the future Louis XVI well known as dauphins before their accession. Today the word appears chiefly in historical writing, biography, and literature — notably Shakespeare's Henry V — and is often capitalized when naming a specific prince. Its shared origin with 'dolphin' makes it a memorable example of how heraldry and geography can shape language.
nounThe eldest son of the king of France and heir apparent to the throne, a title used from the 14th century until the Revolution.

"The young dauphin was tutored in statecraft long before he would ever wear the crown."
"The dauphin was proclaimed king upon his father's death."
"In Shakespeare's Henry V, the arrogant French Dauphin mocks the English king before Agincourt."
Standard plural; occasionally rendered 'dauphins' even for multiple holders of the title across generations.
"Several dauphins died before they could inherit the throne."
France's crown princes were literally named after a dolphin — because a count whose emblem was the dolphin sold his lands to the king on condition the title pass to the heir to the throne.

Etymology of dauphin
The word comes from French dauphin, meaning 'dolphin', ultimately from Latin delphinus and Greek delphis. It became a princely title after Humbert II, Count of Viennois (the Dauphiné), ceded his lands to the French crown in the mid-14th century on condition that the title be borne by the king's eldest son. English adopted the term for this specific French royal usage shortly thereafter.
How dauphin is actually used
Usually capitalized when referring to a specific holder of the French royal title; lowercase when used generically. The word carries strong historical connotations of pre-revolutionary France and is now used almost exclusively in historical or literary contexts.
