In a dictionary, a verb "niburu" is defined as "yowakunaru" or "yowamaru". In order to differentiate between "niburu" and "yowaru", it might be more effective to use information of collocation than to consult only a dictionary. To verify the hypothesis, learners were asked to answer several questions by consulting a dictionary. Then, they were given examples of the usage of "niburu" and "yowaru", and were asked to answer the same questions. There were some learners who had deepened their understanding! however, others got more confused. Therefore, it is necessary to let them think of what (kind of condition) the collocating words mean.
