Ogura, MiekoWang, William S-Y.2017-08-212017-08-212006Studia Anglica Posnaniensia, vol. 42 (2006), pp. 3-300081-6272http://hdl.handle.net/10593/19015We investigate the evolution of homophones and its relation to the evolution of syllable number of words, based on the quantitative analysis on the historical data and simulation. We suggest that homophones are the outcome of arranging form-meaning associations according to Zipf’s law to maximize the referential power under effort for the speaker constraints. We also discuss the neural bases of ambiguity and the relation between ambiguity and robustness in language evolution. Furthermore, we show that homophones are stable and cumulate with the times. To avoid creating homophones, syllable number of words increases, with more recent entry dates of words associated with more syllables. We also explore stability of homophones and instability of synonyms in children’s acquisition process. The mechanism of the evolution of homophones and syllable length of words works cross-linguistically from the emergence of language and goes on at present.enginfo:eu-repo/semantics/openAccessArtykuł
