英语单词词根词缀
英语单词词根词缀 词根: 英语单词构词法的核心部分,在于词根,词的意义主要是由组成单词的词根体现出来的。词根可以单独构成词,也可以彼此组合成词,通过前缀后缀来改变单词的词性和意义。(词根和词缀叫构词语素)也就是说,单词一般由三部分组成:词根、前缀和后缀。词根决定单词意思,前缀改变单词词义,后缀决定单词词性。 词缀: 只能粘附在词根上构成新词的语素,它本身不能单独构成词。粘附在词根前面的词缀称为前缀,粘附在词根后面的词缀称为后缀 例如: 常见的ward这个词根,有“方向”的意思,所以有upward向上,downward向下,forward向前,backward向后。 Pose就是词根是摆放的意思,expose是暴露的意思,EX表示向外,也就是向外摆放就是暴露的意思, danger,名词危险,它的形容词形式是dangerous, 加ous就表示危险的,ous就表示后缀 前缀形式 [prefix]以结合形式出现,与一词、词根或短语开头的一个音或连续几个音相接,或书写中一个字母或连续几个字母用以产生出派生词或变化形式。 一个英语单词可以分为三个部分:前缀(prefix),词根(stem)及后缀(suffix)。单词中位于词根前面的部分就是前缀。前缀,可以改变单词的意思。 常见的前缀有如下几类:第一类:表示正负(或增减)的,如:un-in-im-il-ir-non-mis-mal-(坏,错误)dis-anti-de(剥夺, 分离)-under-re-over-等;第二类表示尺寸的,如:semi-equi-mini-micro-macro-mega-等;第三类表示位置关系,如:inter-super-trans-ex-extra-sub-infra-peri-等;第四类表示时间和次序,如:ante-pre-prime-post-retro-等;第五类表示数字,如:semi-mono-bi-tri-quad-penta-hex-sept(em)-oct-dec-multi-等;其它类别,如:pro-auto-co-con-等。 一.表示否定的前缀 1.dis-加在名词、形容词,动词之前。 disadvantage(缺点)dishonorable(不光彩的)disagree(不同意) 2.in-加在形容词,名词之前 incorrect(不正确的),inability(无能,无力),inaccurate(不准确的) 3.im-加在字母m,b,p之前 impossible(不可能的),impolite(不礼貌的), 4.il-加在以l开头的词前 illegal(非法的),illiterate(文盲的,无文化的)illogical(不合逻辑的) 5.ir-加在以r开头的词前 irregular(不规则的),irresistable(不可抵抗的), 6.un-加在名词,形容词,副词之前 unfinished(未完成的)undoubtedly(无疑地)unemployment(失业)

自己总结的常用英语词根词缀
单词部分: 1.复合词如果后缀是r双写时可以写作l或n,因为r,l,n这三个字母是一个系统内的,如 alternative:二选一的,可供选择的,取舍。 2.al前缀是指“全部的”,也指“外”如alien。 3.ut和ot前缀是out的缩写(两个元音字母保留一个即可)如utmost:最远的,极度 的;n,极限最大可能。Utter,说,发出声音;a,彻底的、完全的。 4.中国人思考文字最大的特点是用形象来思考文字,西文中最大特征是通过声音来描述文 字。所以学习英文是要通过发音来归类进行联想记忆。比如en、el、er的名词后缀基本可通用。这也就是英文能够演化那么多字的原因,通常用首字母相同,尾辅音通假,来构成相同或相近的意思。 5.英语单词的末尾,通常要把词性给表达出来。记忆英文的科学方法是通过词根、词缀和 词源来完成。 6.关于复合后缀,两个不同的后缀表达的词性是有最后一个来决定的。如dominant,d om是词根:顶,in是名词后缀,ant是形容词后缀;所以是形容词。 7.pre和pro两前缀的区别;pre表示静态的:在前既可以指时间上的前也可以表示空间 上的在前;而pro表示往前、向前。 8.ab前缀加强语气,abdomen:腹,下腹(理解为顶出去的东西),另外belly也表示腹部。 9.ent是经典的名词后缀,通常用来表示人的,如student、president(sid=sit),偶尔客 串形容词后缀,如果作为形容词后缀的话其名词后缀就必然是ence;清辅音浊化是一个语言读音趋势,所以把sid演化成sit;还有abide:vt,忍受、容忍、等候,vi(by),遵守、坚持、逗留;也是bite浊化的一个例子(因为人在坚持的时候的动作就是咬),Abide by 遵守于。Obey:顺从,听由摆布(指极度的、强烈的顺从)。 10.al形容词后缀,norm标准;neither既不…也不,表达的也是一种标准的意思,有一种中立 的感觉,所以演化成neutr,加形容词后缀变成中立的,加名词后缀on表示中子;名词后缀on有一种‘子’的意思是从son演变而来的。 11.ish是动词后缀(除了语言后缀English),ol是词根-生长,如abolish;学习词根的 方法有两种宏观扩展和微观分析,其实ol是old的简写,老是变成熟,才能作为生长的意思;有时也会演化成al也是生长的意思,如:coalition结合体、同盟,co是共同的意思即com或con的简写,al生长。 12.ad也是加强语气的前缀,因为是add的缩写,也有人理解为to,也很合理。如adolescent,to 生长,即青春期。 13.odd:古怪的、奇数的,零头;可以想象下古怪的必然很少。 14.tower:塔、城市;由town演变而来,简写作tow或ton,这也解释了为什么那么多的城市 后会有ton这几个字母。类似的还有don、dow其实都是down的简写,如donate:捐赠,endow:捐赠。拆离是简化的原则。 15.en在开头的时候表示加强语气,有使动的含义,在末尾则是名词后缀。 16.his formal clothes make himthe odd one outin the club:他衣冠楚楚使 得他人群中鹤立鸡群。 17.a作为前缀是有两种含义,一种是加强语气是ad的简写,另外就是否定前缀是ab的简写。 如abound:vi,大量存在的,a是否定前缀,bound是边界。Abound in/with。Bounda ry,n,边界。Bound是来源于board板子,boader边界、边缘简化于board。Boat 亦来源于board,再将其去头去尾变成oar即是桨、橹。例句:heabounds in courage。 18.英语单词在单词结尾的地方都有一个要强烈表达词性的字母;如factory:创造+加or
