Pronunciation

  • IPA: /kənˈsɪdəɹəbl̩/, /kənˈsɪdɹəbl̩/[1]

Etymology

It is Middle English, borrowed from Medieval Latin considerabilis (“worthy to be considered”),[2][3][4] from considerāre (“to look at closely”) (see consider), probably originally to observe the stars, from com- and sidus (“star, constellation”).[2]

Earliest recorded meaning

Capable of being considered: about 1449 in the OED, the mid-15th century in Etymonline; the sense is obsolete.[5][2][4]

Semantic evolution

Worthy of regard or attention, important, is from before 1619, and of persons, of consequence or distinction, from 1641.[5][2] Rather large, worthy of notice because of size, is from 1651, the 1650s in Etymonline.[5][2] The American use of considerable as a noun, as in considerable of a surveyor, is from 1685,[5] and was noted as northern by Witherspoon, quoted in Pickering's 1816 vocabulary of Americanisms.[2] As an adverb, considerably, it is obsolete or dialectal.[5]
