The word apron is from the metanalysis of the term “a napron” to “an apron”.
Same with “nickname”. The compound word ekename, literally meaning “additional name”, was attested as early as 1303. By the fifteenth century, the misdivision of the syllables of the phrase “an ekename” led to its reanalysis as “a nekename”. Though the spelling has changed, the pronunciation and meaning of the word have remained relatively stable ever since. [x]
