late 14c., partial re-Latinization of earlier essample , asaumple (mid-13c.), from Old French essemple "sample, model, example, precedent, cautionary tale," from Latin exemplum "a sample," literally "that which is taken out," from eximere "take out, remove" (see exempt (adj.)). Oldest English senses are of "behavior" and "punishment."
In English, the two indefinite articles are a and an. Like other articles, indefinite articles are invariable. You use one or the other, depending on the first letter of the word following the article, for pronunciation reasons. Use a when the next word starts with a consonant, or before words starting in u and eu when they sound like you. Use an when the next word starts with a vowel (a,e,i,o,u) or with a mute h.
The indefinite article is used to refer to something for the first time or to refer to a particular member of a group or class. Some use cases and examples are given below.
