Century Dictionary and Cyclopedia

1. To grant, give, or yield; assign; afford: as, to allow a free passage.

8. Synonyms Allow, Permit, Consent to, Sanction, Suffer, Tolerate. Allow and permit are often used synonymously; but permit strictly denotes a formal or implied assent; allow, the absence of an intent, or even only of an attempt, to hinder.
9. Consent to is formally to permit that which one has the power and generally some disposition to prevent; it implies the assumption of responsibility for that which is thus allowed. Sanction has a secondary sense of permitting with expressed or implied approbation: as, I cannot sanction such a course.
10. Suffer is still more passive or reluctant than allow, and may imply that one does not prevent something, though it is contrary to one's feelings, judgment, or sense of right. To tolerate is to bear with something unpleasant: as, I would not tolerate such impertinence. Many things are tolerated, or suffered, or even allowed, that are not permitted, and many are permitted that are not really consented to, much less sanctioned.
11. To make abatement, concession, or provision: followed by for: as, to allow for the tare.
12. To permit; admit: with of: as, “of this allow,”
13. To praise or commend; approve, justify, or sanction.
