haud aliter ac, not otherwise than.

  d) neque (nec) means and not, neither, nor.

2. a) -que is an enclitic, and is appended always to the second of two
  words connected.  Where it connects phrases or clauses, it is appended to
  the first word of the second clause; but when the first word of the
  second clause is a Preposition, -que is regularly appended to the next
  following word; as,—­

    ob eamque rem, and on account of that thing.

  b) atque is used before vowels and consonants; ac never before vowels,
  and seldom before c, g, qu.

  c) et non is used for neque when the emphasis of the negative rests upon
  a special word; as,—­

    vetus et non ignobilis orator, an old and not ignoble orator.

  d) For and nowhere, and never, and none, the Latin regularly said
  nec usquam, nec umquam, nec ullus, etc.

3.  Correlatives.  Copulative Conjunctions are frequently used correlatively; as,—­

    et ... et, both ... and;

    neque (nec) ... neque (nec), neither ... nor;

    cum ... tum, while ... at the same time;

    tum ... tum, not only ... but also.

  Less frequently:—­

    et ... neque; neque ... et.

  a.  Note that the Latin, with its tendency to emphasize antithetical
  relations, often uses correlatives, especially et ... et, et ... neque,
  neque ... et, where the English employs but a single connective.

4.  In enumerations—­

  a) The different members of a series may follow one another without
  connectives (Asyndeton; see Sec. 346).  Thus:—­

    ex cupiditatibus odia, discidia, discordiae, seditiones, bella
    nascuntur, from covetous desires spring up hatred, dissension,
    discord, sedition, wars.

  b) The different members may severally be connected by et (Polysyndeton). 
  Thus:—­

    horae cedunt et dies et menses et anni, hours and days and months and
    years pass away.

  c) The connective may be omitted between the former members, while the
  last two are connected by -que (rarely et); as,—­

    Caesar in Carnutes, Andes Turonesque legiones deducit, Caesar leads
    his legions into the territory of the Carnutes, Andes, and Turones.

342.  Disjunctive Conjunctions indicate an alternative.

1. a) aut must be used when the alternatives are mutually exclusive; as,—­

    cita mors venit aut victoria laeta, (either) swift death or glad
    victory comes.

  b) vel, -ve (enclitic) imply a choice between the alternatives; as,—­

    qui aether vel caelum nominatur, which is called aether or heaven.
