grandpa

Etymology

The OED, revising the entry in 2015, explains it as from English grand- + pa, formed after grandfather;^[2] the Shorter Oxford also derives it from these elements.^[3] Etymonline treats it as a shortening of the older grandpapa, a childish or familiar form of the same word.^[4]

Earliest recorded meaning

One's grandfather, also as a familiar form of address: ?1785, in Dorothy Kilner's The Rotchfords.^[2] Etymonline dates it to 1814, Merriam-Webster to 1883, and the Shorter Oxford to the late 19th century.^[4][5][3]

Semantic evolution

Besides addressing one's own grandfather, grandpa is used for any elderly man and before a person's surname.^[2] The longer grandpapa is recorded from 1680 by the OED (as grandpappa from 1753 by Etymonline), and the Shorter Oxford calls it now archaic.^[2][4][3] Other familiar forms followed: grandpappy from 1853 and grandpop from 1860, according to Etymonline.^[4]
