attachment Look up attachment at Dictionary.com
mid-15c., "arrest of a person on judicial warrant," from Fr. attachement, from attacher (see attach). Application to property (including, later, wages) dates from 1590s; meaning "sympathy, devotion" is recorded from 1704; that of "something that is attached to something else" dates from 1797 and has become perhaps the most common use since the rise of e-mail.
