translucent

Etymology

It is borrowed from Latin trānslūcēns (“shining through”), the present participle of trānslūceō (“to shine through”),^{[2][3][4][5][6]} formed from trāns- (“through”) and lūceō (“to shine”),^[3][4][7] which Etymonline traces to Proto-Indo-European *leuk- (“light, brightness”).^[3] Barnhart and the Shorter Oxford see the adjective as formed in English beside the earlier translucence, recorded before 1425, on the model of the Latin participle.^[8][9] The OED compares an isolated Middle French translucent of the 14th century.^[2]

Earliest recorded meaning

Allowing light to pass so that things can be seen through it, the same as transparent: 1568, in a poem of W. Stewart in the Bannatyne Manuscript.^[2] Barnhart, Merriam-Webster and Dictionary.com date the word to 1596 or the 1590s,^[8][10][6] in the sense of light that shines through something.^[2][3]

Semantic evolution

At first the word meant either clear and transparent or, of light, shining through or brightly shining, as the Latin did.^[2][11][12] The modern sense, letting light through diffusely, so that objects beyond can't be seen clearly, appears in 1726, in Broome's part of Pope's Odyssey;^[2] Word Origins dates it to the early 18th century,^[11] and Etymonline only to 1785, noting that translucid had the same sense from the 1620s.^[3] The older sense "transparent" is now rare,^[9][2] and the sense of light shining through became obsolete in the 18th century.^[9] Merriam-Webster also records a figurative use, clear or lucid, as of an explanation.^[10][13]
