This is an attempt to determine the role of different parameters in making words sound similar. What is more important, is it sharing the same consonants or the same vowels, is it having the stress on the same syllable or having the same syllabic structure etc? This paper presents an experimental approach to establishing a ranking of word-form similarity parameters, and compares it with the corpus-based approach explained in this conference last year. The implications for phonological and for morphological encoding are discussed.
