Pronunciation

  • IPA: UK /ˈsɪə.riːz/, US /ˈsɪr.iːz/[1]

Etymology

It is borrowed from Latin seriēs (“row, chain, sequence, succession”),[2][3][4] from serere (“to join, link, bind together”),[2][5][6] from Proto-Indo-European *ser- (“to line up”).[2][3] Merriam-Webster relates it to Greek εἴρειν (eírein, “to string together”) and ὅρμος (hórmos, “chain, necklace”).[7][8] Middle English had borrowed the word earlier as serie (“sequence of thoughts”), in the late 14th century.[2]

Earliest recorded meaning

A number of things of one kind following one another in order: 1594 according to the HTOED,[9] 1610s according to Etymonline[2] and 1611 according to Merriam-Webster.[8]

Semantic evolution

A set of books published one after another with something in common has been a series since 1711.[2] The baseball sense, a set of games between the same teams, is from 1862,[2] and a set of radio or television programmes with the same characters from 1949.[2] From 1596 to 1844 the word could also mean the thread of a narrative.[9] The plural is the same as the singular, though the Shorter Oxford records an old plural serieses.[4] Seriatim is from the 17th century and serial from the 19th, first of a story published in parts.[6]
