Category:English nouns which have interacted with their indefinite article
Definition from Wiktionary, the free dictionary
In the histories of certain English words, there has been a re-analysis due to the fact that the English indefinite article has two forms: a, and an. This phenomenon is known as rebracketing or “juncture loss”.
The results have been in both directions: “a napron” evolving into “an apron”; and “an eke-name” evolving into “a nickname”.
Note that juncture loss may have occurred in a different language before a word reached English; for example, orange did not develop in English from *a norange, but rather the juncture loss occurred in Old French and Anglo-Norman orenge, or possibly in Italian.
