We may also, if we choose, call 'sang', the preterit of the verb 'to sing', an amalgam, although it is not likely to have resulted from a process of amalgamation. This process is not necessarily carried through so that it becomes impossible to distinguish one 'signifiant' from another: in Slavic languages, amalgamating processes have, at different periods, begun to blur the boundaries between the radical moneme 'ruk-' ‘hand’ and the following derivational monemes or case-endings; this as resulted in yielding different forms for the radical: in Czech, for instance, 'ruk-' in the nominative singular 'ruka', 'ruc-' in the locative 'ruce', and 'ruč-' in the adjective 'ručni'.
