As Le Bel said, stating it as a fundamental principle of analysis, 'there is no group of which the parts have not existed separately before being grouped together'; this enabled him to reduce all words to syllabic elements in which the old forgotten names at last made their reappearance the only vocables that possessed the possibility of existing side by side with the verb to be: Romulus, for example, comes from Roma and moliri (to build); and Roma comes from ro, which denoted strength (robur) and ma, which denoted magnitude (magnus).
