To free from trammel (a net or anything that restricts movement); to liberate from constraints.
From dis- + entrammel (from en- + trammel, from Old French tramail 'three-mesh net'). Originally a fishing term that became metaphorical.
A trammel was literally a fishing net, so 'disentrammel' originally meant freeing a fish from a net—but poets and philosophers loved the metaphor for freeing the mind from restrictions.
