|Naval officer ranks|
Admiral is one of the highest ranks in some navies. In the Commonwealth nations and the United States, a "full" admiral is equivalent to a "full" general in the army, the airforce and is above vice admiral and below admiral of the fleet, or fleet admiral. In NATO, admirals have a rank code of OF-9 as a four-star rank.
The word admiral in Middle English comes from Anglo-French amiral, "commander", from Medieval Latin admiralis, admirallus. These evolved from the Arabic amīral (أمير الـ) – amīr (أمير), “king, prince, chief, leader, nobleman, lord, a governor, commander, or person who rules over a number of people,”and al (الـ), the Arabic article answering to “the.” In Arabic, admiral is also represented as Amīr al-Baḥr (أمير البحر or البحر أمير), where al-Baḥr (البحر) means the sea.
The 1818 edition of Samuel Johnson's A Dictionary of the English Language, edited and revised by the Rev. Henry John Todd, states that the term “has been traced to the Arab. emir or amir, lord or commander, and the Gr. ἄλιος, the sea, q. d. prince of the sea. The word is written both with and without the d, in other languages, as well as our own. Barb. Lat. admirallus and amiralius. V. Ducange. Barb. Græc. ἄμηρχλιος. V. Meursii Gloss. Græco-Barbarum, edit. 1610. p. 29. Fr. admiral and amiral. Dan. the same. Germ. ammiral. Dutch, admirael or ammirael. Ital. ammiraglio. Sp. almirante. Minsheu, in his Spanish Dictionary, says ‘almiralle is a king in the Arabian language.’ Amrayl is used by Robert of Gloucester, in the sense of a prince, or governour.”
The quote from John Minsheu’s Dictionarie in Spanish and English (1599), given in Johnson’s Dictionary, has been confirmed as being accurate. Additionally, the definition of Amīr (أمير), as given in Edward William Lane's Arabic-English Lexicon, concurs, in part, with Minsheu's definition, stating that the term means “One having, holding, or possessing, command; a commander; a governor; a lord; a prince, or king.”
While other Greek words of the period existed to indicate “belonging to the sea,” or “of the sea,” the now obsolete Gr. ἄλιος mentioned in Johnson's Dictionary is expressly defined as "of the sea, Lat. marinus, epith. of sea-gods, nymphs, etc."
Though there are multiple meanings for the Arabic Amīr (أمير), the literal meaning of the phrase Amīr al-Baḥr (أمير البحر) is “Prince of the Sea.” This position, versus “commander of the sea,” is demonstrated by legal practices prevailing in the Ottoman Empire, whereas it was only possible for Phanariots to qualify for attaining four princely positions, those being grand dragoman, dragoman of the fleet, and the voievods of Moldavia and Wallachia. Those Phanariots who attained the princely position of dragoman of the fleet served under the Ottoman admiral having administration of the Aegean islands and the Anatolian coast.
Modern acknowledgement of the phrase Amīr al-Baḥr (أمير البحر) meaning “Prince of the Sea” includes a speech made in an official U.S. military ceremony conducted in an Arabic port, and a news article published by an Arabic news outlet: On 24 May 2012, in a change of command ceremony aboard aircraft carrier USS Enterprise (CVN 65), while docked at Khalifa Bin Salman Port, Bahrain, U.S. Marine Corps Gen. James Mattis, Commander, U.S. Central Command, introduced Vice Admiral Mark I. Fox as “Admiral Fox, the prince of the sea, emir of the sea – to translate ‘admiral’ from the Arabic to English;” On 04 Feb 2021, in an announcement of his coronavirus-related death, the Arabic news website Saudi 24 News referred to Admiral Edmond Chagoury by the title “Prince of the Sea.”
An alternate etymology proposes that the term admiral evolved, instead, from the title of Amīr al-Umarāʾ (أمير الأمراء). Under the reign of the Buyid dynasty (934 to 1062) of Iraq and Iran, the title of Amīr al-Umarāʾ, which means prince of princes, came to denote the heir-apparent, or crown prince.
This alternate etymology states that the term was in use for the Greco-Arab naval leaders of Norman Sicily, which had formerly been ruled by Arabs, at least by the early 11th century. During this time, the Norman Roger II of Sicily (1095–1154) employed a Greek Christian, known as George of Antioch, who previously had served as a naval commander for several North African Muslim rulers. Roger styled George in Abbasid fashion as Amir of Amirs, or Amīr al-Umarāʾ, with the title becoming Latinized in the 13th century as ammiratus ammiratorum.
The Sicilians and later Genoese took the first two parts of the term and used them as one word, amiral, from their Aragon opponents. The French and Spanish gave their sea commanders similar titles while in Portuguese the word changed to almirante. As the word was used by people speaking Latin or Latin-based languages it gained the "d" and endured a series of different endings and spellings leading to the English spelling admyrall in the 14th century and to admiral by the 16th century.
The word "admiral" has come to be almost exclusively associated with the highest naval rank in most of the world's navies, equivalent to the army rank of general. However, this was not always the case; for example, in some European countries prior to the end of World War II, admiral was the third highest naval rank after general admiral and grand admiral.
The rank of admiral has also been subdivided into various grades, several of which are historically extinct while others remain in use in most present-day navies. The Royal Navy used the colours red, white, and blue, in descending order to indicate seniority of its admirals until 1864; for example, Horatio Nelson's highest rank was vice-admiral of the white. The generic term for these naval equivalents of army generals is flag officer. Some navies have also used army-type titles for them, such as the Cromwellian "general at sea".
While the rank of vice admiral is used in most of NATO countries, it is ranked differently depending on the country.
|NATO code||Country||English equivalent|
|OF-10||Italy||Admiral of the Fleet||Fleet admiral|
|OF-9||Belgium, Bulgaria, Canada, Croatia, Denmark, Estonia, France, Germany, Montenegro, Norway, Poland, Portugal, Romania, Slovenia, Turkey,||Admiral||Admiral|
|OF-8||Albania, Spain||Vice admiral||Vice admiral|
The rank insignia for an admiral often involves four stars or similar devices, or three stripes over a broad stripe, but there are many cases where the insignia do not involve four stars or similar devices. There are sleeve insignia and shoulder insignia.
