Bybee’s model makes predictions about and explains synchronic, diachronic and typological patterns within languages, such as which variants will occur in which contexts, what forms they will take, and about their diachronic consequences. Using the linguistic phenomenon of splits (when a word starts to show subtle polysemy, and morphological possibilities for the originally single form ensue), Bybee proves that even irreducibly irregular word-forms are seen to be non-arbitrary when the context it occurs in is taken into consideration in the very representation of morphology. Simultaneously, she shows that even seemingly regular allomorphy is context-sensitive. Splits also aligns with the idea that linguistic forms cannot be studied as isolated entities, but rather in relation to the strength of their attachment to other entities.<ref>{{cite book |last1=Luce |first=P.A.|last2=Pisoni |first2=D.B|last3=Goldinger |first3=S.D.|chapter=Similarity neighborhoods of spoken words |editor=G.
