Word and Object synonymy of native occasion sentences even of non-observational kind can be settled if raised, but the sentences cannot be translated.' " To go beyond these boundaries of translation by stimulus meaning, the linguist uses analytical hypotheses, in which he uses the steps (1) - (4) to equate parts of the native sentences to English words or phrases. Using the analytical hypotheses the linguist can form new sentences and create a translation manual. In Chapter 2 of "Word and Object", Quine shows that the total apparatus of grammatical and semantic devices in a language is not objectively translatable into foreign languages.
Square-free word first difference of the Thue–Morse sequence. That is, from the Thue–Morse sequence one forms a new sequence in which each term is the difference of two consecutive terms of the Thue–Morse sequence. The resulting square-free word is Another example found by John Leech is defined recursively over the alphabet {"a, b, c"}. Let formula_1 be any word starting with the letter "a". Define the words formula_2 recursively as follows: the word formula_3 is obtained from formula_4 by replacing each "a" in formula_4 with , each "b" with , and each "c" with . It is possible to check that the
