Abstract The impact of power in the criminal court discourse and the interrogation process is manifested in many factors such as context-specific conditions and differences in social position between a police investigator and the accused. This study intends to use politeness strategies by Brown and Levinson (1987) to explore and describe the role of politeness in the interrogation process. The aim of this study is to describe the relationship between power and politeness in promoting the interrogation process because politeness is embedded in power relations. Corpus consisted of eleven transcripts of the hearing randomly selected from criminal cases in public justice administration in Bushehr. The results showed that with the observance of politeness (Brown and Levinson's strategies), the interrogation route could not be well advanced, because the defendants refrain from answering questions due to lack of pressure and threat. But with pressure and harshness of the signs of power, the interrogation route can be well advanced.

Abstract A motivated derivational word is a word that its meaning is the result of the meaning of word stem and derivational affixes. In this paper, the hypothesis is tested that by the passage fo time,motivation would be reduced and for this purpose, four itinerary passages from present and four equal passages from 200 years before are chose to understand ,under comparisons and statistical considerations, from 200 years befor, derivational words in Persian language have been more motivated or not. Comparison of results show that a meaningful increase is evident in the number of derivational words in present time, in the number of motivated words and in the number of partially motivated derivational words .therefore,we would say that from two hundred years before, derivational words in Persian language have been more motivation.
