a person who associates or cooperates with another; supporter. As used in
Scientology,
ally means someone who protects a person who is in a weak
state and becomes a very strong influence over the person. The weaker person, such as a child, even
partakes of the
characteristics of the
ally, so that one may find that a person who has, for instance, a bad leg, has it because a protector or
ally in his youth had a bad leg. The
word is from
French and
Latin and means to
bind together.
