Bouvier's Law Dictionary, Revised 6th Ed (1856):

ALIENATE, aliene, alien. This is a generic term applicable to the various
methods of transferring property from one person to another. Lord Coke, says,

(1 Inst. 118 b,) alien cometh of the verb alienate, that is, alienum facere
vel ex nostro dominio in alienum trawferre sive rem aliquam in dominium
alterius transferre. These methods vary, according to the nature of the
property to be conveyed and the particular objects the conveyance is
designed to accomplish. It has been held, that under a prohibition to
alienate, long leases are comprehended. 2 Dow's Rep. 210.
