Some while ago I had to change my mind on the shape of the plural definite article in Rhodrese. Ever since the inception of the lang I’d thought the plural definite article was il, but with the rule that unstressed e and unstressed i are pronounced alike as [ɪ] a plural il would be homophonous with the masculine el, and I can clearly not have that! Better then to have the plural article as li, with the prepositions + article contractions becoming dilli, alli, polli etc. Needless to say the plural article before words beginning in a vowel remains gl’.
This also offers a clue to the demise of distinct feminine forms, for surely the feminine plural article was originally le but became homophonous with the masculine li. The abolition of le was surely one of Bernual’s reforms.
