2.  Correlatives.  Disjunctive Conjunctions are often used correlatively; as,—­

    aut ... aut, either ... or;

    vel ... vel, either ... or;

    sive ... sive, if ... or if.

343.  Adversative Conjunctions.  These denote opposition.

1. a) sed, but, merely denotes opposition.

  b) verum, but, is stronger than sed, but is less frequently used.

  c) autem, but on the other hand, however, marks a transition.  It is
  always post-positive.

DEFINITION.  A post-positive word is one that cannot begin a sentence, but is placed after one or more words.

  d) at, but, is used especially in disputation, to introduce an opposing
  argument.

  e) atqui means but yet.

  f) tamen, yet, usually stands after the emphatic word, but not always.

  g) vero, however, indeed, in truth, is always post-positive.

2.  Note the correlative expressions:—­

    non solum (non modo) ... sed etiam, not only ... but also;

    non modo non ... sed ne ... quidem, not only not, but not even; as,—­

    non modo tibi non irascor, sed ne reprehendo quidem factum tuum, I not
    only am not angry with you, but I do not even blame your action.

  a.  But when the sentence has but one verb, and this stands with the
  second member, non modo may be used for non modo non; as,—­

    adsentatio non modo amico, sed ne libero quidem digne est, flattery is
    not only not worthy of a friend, but not even of a free man.

344.  Illative Conjunctions.  These represent the statement which they introduce as following from or as in conformity with what has preceded.

1. a) itaque = and so, accordingly.

  b) ergo = therefore, accordingly.

  c) igitur (regularly post-positive[58]) = therefore, accordingly.

2.  Igitur is never combined with et, atque, -que, or neque.

345.  Causal Conjunctions.  These denote cause, or give an explanation.  They are nam, namque, enim (post-positive), etenim, for.

346.  Asyndeton.  The conjunction is sometimes omitted between cooerdinate members, particularly in lively or impassioned narration.  Thus:—­

  a) A copulative Conjunction is omitted; as,—­

    avaritia infinita, insatiabilis est, avarice is boundless (and)
    insatiable;

    Cn.  Pompejo, M. Crasso consulibus, in the consulship of Gnaeus Pompey
    (and) Marcus Crassus.

    The conjunction is regularly omitted between the names of consuls when
    the praenomen (Marcus, Gaius, etc.) is expressed.
