Origin and History
Etymology of Ally
The word ally has a long history.
Merriam-Webster traces the noun and verb to Middle English allien, from Anglo-French alier, and ultimately from Latin alligare, meaning “to bind.” The idea of joining or binding together is closely connected to the modern meaning of forming an alliance.
Merriam-Webster records the first known use of ally as a verb in the 14th century and as a noun in the 15th century.
Etymology of Alley
Alley has a completely different history.
Merriam-Webster traces the word to Middle English and Anglo-French alee, from aler, meaning “to go.” It originally referred to a walkway or passage.
The word later developed meanings connected with narrow passages, streets, garden walks, and playing areas.
So although ally and alley look similar today, they do not come from the same word.
