Etymology

It is inherited from Middle English blok, blokke,[2][3] borrowed from Old French bloc (“log, block of wood”),[2][4][5] from a Germanic source,[2] Middle Dutch blok (“trunk of a tree”),[4][3][6] of unknown ultimate origin.[5][6] Related words are Old High German bloh, Middle Low German block and Middle Irish blog “fragment”.[3][5] Etymonline traces it to Proto-Indo-European *bhelg- (“a thick plank, beam”), the root of balk,[2] and Merriam-Webster perhaps to Old High German bliuwan “to beat”, akin to blow.[3] It was an Anglo-French surname, Blocker, from 1212, and appears in the compound blockbord in 1323.[4] The verb is partly from the noun and partly from French bloquer.[5][7]

Earliest recorded meaning

A log of wood, part of a tree trunk, a stump: about 1305 in the OED,[8] the early 14th century in Etymonline,[2] and 1390 in Barnhart.[4]

Semantic evolution

By the late 15th century the word was used of any solid piece.[2] A block for chopping meat or wood is from about 1485, and the block on which the condemned were beheaded from 1541;[8] the phrase put one's head on the block is from the mid-16th century.[9] A stupid person was compared to a block from about 1410.[8] A pulley in a wooden case is from about 1400, hence block and tackle (1825).[2] A block of buildings bounded by four streets is North American from 1796;[2][9] Bartlett (1848) called it “a very useful” American term.[2][10] The auction block on which slaves were sold is from 1842.[2] The verb, “to obstruct”, is from about 1425,[8] the 1590s in Etymonline,[2] and “to blockade” from 1591.[8] A block in cricket is from 1772 and in American football from 1889.[2] A mental block is a later development of the noun “obstruction” (1831).[2] The political bloc is the same French word readopted in 1903.[4][9]
