語源

    Reassignment of Classical Latin ācer from the third declension to the first/second, facilitated by the fact that the nominative singular ācer can itself be taken as a second declension form, initially yielding a paradigm ācer/ācra/ācrum (compare Classical Latin niger/nigra/nigrum 'black'). The wide distribution of its descendants across the branches of Romance implies that its presence in the oral language considerably predates its appearance in writing.
