  6. Classes of Syntactic Relations • 1) actant relations; • 2) attributive relations; • 3) coordinative relations; • 4) auxiliary relations December 14, 2009. Lectures 9-10

  7. Class of Coordinative Relations 1) Coordinative Relation proper 2) Sentential-Coordinative Relation 3) Coordinative-Conjunctive Relation 4) Sequential Relation December 14, 2009. Lectures 9-10

  8. Coordination as Type of Subordination Why? • there is no distinct boundary between subordination and coordination: slow and sure  slow but sure  slow if sure  slow though sure brave new world  brave, new world  brave and new world rus. Ivan iMarijaprishli = Ivan s Mariejprishli Ivan and Maria came vs. Ivan with Maria came David and Goliath fought = David fought with Goliaph Sarkozy, Merkel to improve bilateral ties <to hold talks> December 14, 2009. Lectures 9-10

  9. Coordination as Type of Subordination Why? • there is no distinct boundary between subordination and coordination: John Hopkins, University Professor and Member of the Parliament, once said… = John Hopkins, University Professor, Member of the Parliament, once said… December 14, 2009. Lectures 9-10

  10. Coordination as Type of Subordination Why? • they say that coordinated words are symmetrical and permutative , while subordinated ones are not: John and Mary = Mary and John vs. Lesson of wisdom ≠ Wisdom of lesson However, this is not always so: Try and catch me ≠ Catch and try me. Moreover: and instantiates a valency of try: Try and catch me = Try to catch me December 14, 2009. Lectures 9-10

  11. Coordination as Type of Subordination Russian has many more verbs that have such a property. Pytat’sja ‘try’ is not among them but its approximate synonym, starat’sja ‘do one’s best’, is: On nakonec postaralsja i sdal ekzamen ‘Finally he did his best and passed the exam” On oshibsja i poshel v protivopolozhnuju storonu ‘He made a mistake and went the opposite way’ : interpretation verb Izlovchilsja i vyrvalsja iz ruk policejskogo ‘he contrived to tear himself away from the policeman’ December 14, 2009.
