SOME PRE-HISTORIC CHANGES
these types of Nouns the long vowel was carried by Analogy all through the declension (Acc. monitōrem, etc.), though by the time of Cicero the final syllable of the Nom. had been shortened (§ 180). Contrast with these the Weakened form -tr- on which the corresponding Feminines are based, e.g. Acc. moni-tr-īc-em (§ 231). In nouns like homo from older homō (§ 95) the Strengthened Deflected form appears in the Nom. Sing. But in some words, such as sermō ‘conversation,’ tēmō ‘pole of a chariot,’ the Strengthened form spread through all the cases.
