<注釋>Perhaps more than once one may have wonderedwhy the wordperiod has the sense .punctuation mark ( . ). as well as some of its other senses having to do with time.The answer to this question lies in the senses of the Greek wordperiodos from which our word is descended. Periodos, made up of peri-, .around,. and hodos, .way,. meant such things as .going round, way round, going round in a circle, circuit,.and with regard to time .cycle or period of time..The word also meant .the period of menstruation..In rhetoric it referred to .a group of words organically related in grammar and sense..The Greek word was adopted into Latin asperihodos with only its rhetorical sense and one other sense,but in Medieval Latin it reacquired senses it had in Greek,such as .cycle,. and acquired a new sense,.a punctuation mark used at the end of a rhetorical period..Although this sense is recorded in Medieval Latin,it is not recorded in English until '09.But the wordperiod had entered Middle English from Medieval Latin and Old French, first being recorded in a work written around 425in the sense .a cycle of recurrence of a disease..
或許任何人都會不止一次的發出疑問，為什么period 有.標點符號（。）.的意思， 同時其它意思與時間有關。此問的答案來自我們的單詞源自的希臘語單詞periodos 的意思。 Periodos ，由意為.周圍.的 peri- 和意為.方式.的 hodos 組成， 該詞意味著.圍繞…走，圍繞…的路，轉圈走，圍繞，.同時也指時間，意為.一段時間或時間周期.。此詞也意為.經期.。在修辭學中指.一組在語法和詞意上有機相連的詞。.這個希臘詞作為perihodos 被拉丁文所採用， 僅帶有修辭和一個其他的意思，但在中世紀拉丁語中它重新得到了它在希臘語中的意思，例如.周期.，後來又得到一個新的意思，即.用於修辭部分末尾的標點符號.。儘管此意在中世紀拉丁語中有記載，但直到'09年才在英文中有記載。而period 從中世紀拉丁文和古法文中進入中世紀英文， 並首次記載於約425年所著的作品中，意為.疾病發作的周期.
