‖ ˈtrimoda neˈcessitas Old Eng. Hist.
Usually erron. trinoda n.
[Late L., = trimoda, fem. of trimodus adj. ‘of three kinds’, (Isidore Orig. ii. xvii, De trimodo dicendi genere), f. tri- + modus mode, manner, necessitas necessity, exigency, need, obligation.
The phrase occurs only once, viz. in an OE. Charter attributed to K. Cædwalla of Wessex, 685–88, but actually in a MS. of about 975. Thence erroneously cited in 1614 by Selden as trinoda necessitas, whence in other 17th c. legal antiquaries and dictionaries, and thence in 19th c. historians and legal writers, and usually taken to mean three-knotted from L. nōdus knot. See article by W. H. Stevenson in Eng. Hist. Rev. Oct. 1914; also G. J. Turner in Encycl. Brit. (ed. 11) XXVII. 287/1.]
A collective appellation for the three great obligations upon land-holders in Anglo-Saxon times, of maintaining bridges and fortresses, and rendering military service, in OE. brycgbót, burhbót, and fyrd. (There was no collective OE. term for the three.)
