Origin: 15th century ;

 Middle English ele, eill, ile, ilde "lateral division of a church on either side of the nave, usually divided from the nave by pillars," borrowed from Anglo-French ele, esle, aile, ile "wing, wing of a building, lateral division of a nave" (continental Old French ele "wing, wing of a building"), going back to Latin āla "wing" ;

  * Note : The Middle English forms ile, ilde show assimilation to ile, ilde "island" (see: {isle:1|isle:1})—the rows on either side of the nave perhaps being thought of as isolated from the rest of the church—and effectively supplant ele, eill, etc. in the sixteenth century. The in ilde is a secondary extrusion (compare {mold:3|mold:3}). In early Modern English ile competes orthographically with a variety of other spellings, as ayle/aile, which appears to have regressed to the sense "wing" and adopted the Middle French spelling aile, an etymologizing variant of earlier ele; and isle, which copies the spelling of {isle:1|isle:1}. The now standard spelling aisle looks like a merger of aile and isle. Samuel Johnson enters aisle in his dictionary (1755) with some reluctance: "Thus the word is written by [Joseph] Addison, but perhaps improperly; since it see:ms deducible only from either aile, a wing, or allée, a path; and is therefore to be written aile." As Johnson was likely aware, aisle had developed a broadened sense "passage between pews in the middle of a church" that copies a now out-of-use sense of {alley:1|alley:1}. The still broader extensions "passage between seats in a train, bus or airplane" and "space between rows of items in a department store or supermarket" first appeared in American English.;
