Historical Linguistics and Language Families 10, Exercise 3: your own plan

There is no single answer. A good plan has these parts:

  - the two languages named;
  - a list of basic words to compare (numbers, body parts, water, fire);
  - the sources: a dictionary or etymological reference for each language,
    and a reference such as an encyclopedia article for the family;
  - the checks for chance, loanwords and contact (a loanword from the other
    language would break the comparison);
  - what would make you doubt the result: too few cognates, no regular
    correspondence, or evidence that the shared words were borrowed.

Self-check: could someone else repeat your comparison from the plan, and could
the result be proved wrong? If not, add the missing steps.
