<注释>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..
或许任何人都会不止一次的发出疑问，为什么period 有.标点符号（。）.的意思， 同时其它意思与时间有关。此问的答案来自我们的单词源自的希腊语单词periodos 的意思。 Periodos ，由意为.周围.的 peri- 和意为.方式.的 hodos 组成， 该词意味着.围绕…走，围绕…的路，转圈走，围绕，.同时也指时间，意为.一段时间或时间周期.。此词也意为.经期.。在修辞学中指.一组在语法和词意上有机相连的词。.这个希腊词作为perihodos 被拉丁文所采用， 仅带有修辞和一个其他的意思，但在中世纪拉丁语中它重新得到了它在希腊语中的意思，例如.周期.，后来又得到一个新的意思，即.用于修辞部分末尾的标点符号.。尽管此意在中世纪拉丁语中有记载，但直到'09年才在英语中有记载。而period 从中世纪拉丁文和古法语中进入中世纪英语， 并首次记载于约425年所著的作品中，意为.疾病发作的周期.
