linguistics1-9  Exercise 3: Three Registers
===========================================

One possible set:

  To a manager:   I apologise, but I will be late this morning, as my train
                  has been cancelled. I expect to arrive by ten.
  To a colleague: Running late, my train's been cancelled. Should be in by
                  ten.
  To a friend:    Train's cancelled, ugh. Be there in a bit.

Features that differ (any two):

  - Contractions and omitted subjects ("Running late", "Train's") appear as
    the register gets less formal.
  - Vocabulary: "apologise" and "expect to arrive" against "ugh" and
    "in a bit".
  - Sentence length and structure: full clauses against fragments.
  - Politeness markers: the apology and "I will" in the formal version.

Register built into grammar (one example is enough):

  German     du (friends) against Sie (manager): the pronoun and the verb
             ending both change (kommst / kommen).
  Hungarian  te against Ön, with different verb forms.
  Japanese   plain forms against polite -masu forms against honorific
             keigo; the whole verb changes.
  French     tu against vous.

Your wording will differ; check that the formality matches the audience.
