五个常见英语否定前缀用法辨析

令狐文艳

一、un-是来自英语本族语的前缀,其英文含义为not, the opposite of。它是5个否定前缀中运用最为广泛的一个,构词能力相当强。通常加在形容词、副词、名词、动词及分词之前,表示否定意义和相反的动作。该词缀的用法有下列几种情形:

1. un-加在词头为in-或im-的单词前。 a.加在in-前:uninfluential uninformative unintell igent unintentional unintelliglble uninterpretable uninteresting un involved b.加在im-前:

unimportant unimaginable unimpre ssible unimpressive unimproved unimagined

2. un-加在以-able,-ful,-like,-ly,-some,-ing,-ed 结尾的单词前。 a.加在-able结尾的词前:

unfinishable undesirable unmatchable unexplai nable unexpectable untranslatable

b.加在-ful结尾的词前:

unhealthful unfruitful unhelpful unmindful unpainful unskillful

unsucceessful unuseful

c.加在-like结尾的词前:

unstatesmanlike unsportsrnanlike

d.加在-some结尾的词前:unhandsome untroublesome

e.加在-ly结尾的词前:

unbrotherly unshapely unsightly unw orldly unwomanly unmannerly

f.加在-ing结尾的词前:

unharming ungiving unloving u nfeeling unmeaning unmoving

g.加在-ed结尾的词前:

unmoved unspoiled unhandled unfixed unexpressed unexpected

3. un-还可以加在-ed分词+介词或副词的词前:

unheard-of unhoped-for unmade-up uncared-for

4. “un+名词+ful”形式的形容词常和“名词+less”形式的形容词表达相同的意思。例如:unfaithful=faithless,unuseful=useless等。但也有例外,如hopeless,thoughtless就没有相应的unhopeful,unthoughtful。

5. 在现代英语中,un-的使用范围日趋广泛,几乎可以任意地加在形容词前构成反义词。如:

unalike, uncool, uncooperative等。

6. 近年来,un-又增添了新的含义。如:unbook指买来不是为读而是为送人的书;unperson指政治上失宠并遭清洗的官员。

二、in-是来自拉丁语的前缀,其英文含义为the opposite of, not, 表示“相反”的意思。常加在形容词前构成反义词。除了in-这一基本形式外,由于音同化的影响,还有其它3种词素变体(allomorph):il-, im-和ir-, 共有4种形式。其用法有下面4条细则:

1. il-用于l开头的单词,如:illegal illiterate illogical

2. im-用于b, m, p开头的单词,如:imbalance immortal imperfect

3. ir-用于r开头的单词,如:

irresponsible irregular irrelevant

4. in-用于其它字母开头的单词,如:

inactive incorrect inexperience inhuman in justice insecure

拉丁语前缀in-在过去非常盛行,现在却变为了非能产性的,不能再与英语本族语的同义词前缀un-抗衡。在现代英语中,几乎所有的形容词和分词都可以加un-这个前缀。因此,在用法上要注意in-和un-的区别。

(1)in-这个前缀来自拉丁语,因而明显地带有拉丁词尾-ate,

-ant,-ent,-ite,-ible等的词用in-,例如:inappropriate,incessant,incoherent,indefinite,invisible,但也有例外的,如:unfortunate。

(2)以im-或in-为词头的单词不能再用in-,只能用un-,例如:unimaginable,unimpressive,uninfluential,unintelligent。(3)以-able,-ed,-ful,-ing,-like,-ly,-some结尾的词多用un-,例如:unfashionable,unhatched,unsuccessful,unharming,unstatesmanlike,unworthily,untroublesome。

(4)凡是已固定加了拉丁前缀in-的形容词,通常不能改用un-,例如:inactive,inaudible,infillable。

四、dis-是来自拉丁语的前缀,其英文含义为not, the opposite of,一般加在抽象名词、形容词及动词前构成“否定”、“相反”、“除去”等意思。

1. dis-加在名词前:

disharmony dishonesty disbelief

2. dis-加在形容词前:

disrespectful distrustful disloyal dislikable

3. dis-加在动词前:

disapprove disbelieve disimprove disobey

而mis-加在动词、名词前,例词misunderstand误解、misjudge误判、misleading误导、misfortune不幸;

初中英语形容词否定前后缀语法归纳

☆特别提醒:

◇初中阶段,形容词否定前缀大多以un-构成,除去少数几个以-less否定后缀结尾外,不是以un-否定前缀构成的形容词基本上只有7个。

即上表中以dis-, im-, in-, ir-开头的七个例词。换言之,如果把这七个词烂熟于心,那么记忆形容词否定前缀就将事半功倍。

◇以un-开头的形容词其前面的冠词用的是an。例如:an unusual boy。

◇dis-否定前缀除了形容词dishonest外,还常常用在动词前构成否定形式,如dislike, disagree, disappear等。
