Forms

blocus m (invariable)[1] Early forms include Old Walloon blokehus (1350), blochus (1376) and bloxhus (1380), Picard blocus (1397), blocquehuys (1485, Mons), blochuysse (1584) and Middle French bloccus (1547).[2][3]

Etymology

It is borrowed from Middle Dutch blochuus (“house built of beams, small fort”), a compound of bloc (“log, block”) and huus (“house”).[2][3][4][5][6] The Middle Dutch word corresponds to German Blockhaus, the source of French blockhaus.[2][3]

Littré took the word for the German form.[7] The TLFi and Rey prefer a Middle Dutch source to the Middle High German one put forward by Diez and the REW, because the early records all come from the regions bordering on Dutch-speaking territory, and because later local forms of the 15th and 16th centuries reflect modern Dutch blokhuis.[2][3] The modern sense of a blockade is not found in Dutch; it is a French development.[2]

Earliest recorded meaning

The first record is Old Walloon blokehus in 1350, cited by the FEW without a quotation, meaning a house built of timber; the spelling blocus is found in a Picard document from Douai in 1397.[2][8]

Semantic evolution

The sense of a timber house was alive in north-eastern France in the 14th and 15th centuries.[3] From 1376, in the records of Liège, the word named a small fort built by besiegers to cut a besieged town off from the outside; this military sense reached general French in 1547, in Jean Martin's translation of Vitruvius, and was given up in the 17th century.[2][3] Agrippa d'Aubigné still wrote of a town besieged de vingt-deux blocus “with twenty-two forts”.[7]

The stress then moved to what the forts were for, and by metonymy the word came to mean the cutting off of a town, port or position itself (1663, Corneille).[2][3] Blocus continental names Napoleon's system, set up by a decree dated 21 November 1806, for shutting Britain out of the European continent.[2][3] In the 20th century the word was extended to the means used to prevent normal trade with another country (blocus économique).[3][4] Rey notes that from the 19th century the noun gave new life to the verb bloquer.[3] In Belgian French blocus is the period of intense study before examinations.[3][1]
