alone

Sole. The German allein is used in like manner thus, alleinbesitz, sole, exclusive possession; alleinhandel, sole trade, monopoly. Mr. Todd says, the English word was formerly written all-one, and was used in this sense by old writers. Mr. Pickering says, "It is often heard from our pulpits in expressions like the following: The alone God; the alone motive, &c. It is now rarely used, although I heard it in a prayer during the present year (1848). The following examples from English writers cited by Johnson and Pickering show its use:

God, by whose alone power and conversation we all live, and move, and have our being.--Bentley.

The Legislature never pretended to omnipotence; that is the alone attribute of the people.--British Critic, Vol. IX. p. 234.
