A prefix is a letter or set of letters added to the beginning of a word to change its meaning, such as 'un-' (not) in 'unhappy' or 're-' (again) in 'redo'; common prefixes include 'co-' (with), 'dis-' (not), 'im-' (not), 'in-' (not), 'mis-' (wrongly), 'non-' (without), 'post-' (after), 'pre-' (before), 're-' (again), 'semi-' (half), 'sub-' (under), 'tri-' (three), 'un-' (not), and 'uni-' (one), which help expand vocabulary by creating new words with modified meanings.

ENGLISH LANGUAGE: PREFIXESAdded:
dear students welcome to the online class of english language the third topic is prefixes children before referring to the book let's understand what are prefixes children a prefix is a group of letters we add to the front of a word prefixes change the meaning or purpose of the word for example an plus kind is equal to unkind so the word has become its opposite meaning as you can clearly see on the screen other examples dis plus connect is equal to disconnect re plus do is equal to redo co plus exist is equal to coexist so children in simple words prefixes are letters which we add to the beginning of a word to make a new word with a different meaning prefixes can for example create a new word opposite in meaning to the word the prefix is attached to they can also make a word negative or express relations of time place or manner you can see on the screen some examples now children open your book to page number 108 now let's read the definition a prefix is a letter or a set of letters that are added before a word to change its meaning so children simply remember one thing that a prefix is a letter or a set of letters that we add before a word and when we add it before a word a new word is formed and its meaning changes now children here is a list of prefixes with their meaning and examples let's go through the list the first prefix is go that means with so examples are co-worker co-pilot next prefix is d which means away from and the examples are defrost derail next we have dis and this means not and examples are disagree disappear so children when you add this to agree it becomes disagree and it becomes a negative word i hope you are understanding the next prefix is m and m means cause 2 for example embrace embed next we have n n means put into for example enclose engulf next we have x x means out of for example exhale export next we have extra extra means beyond for example extraordinary extraterrestrial next we have four four means before for example forecast forehead next we have ill means not for example illegal illiterate so not legal not literate so when we add ill there is a new word that means illegal illiterate similarly m also means not for example impossible impolite next we have in and children again in means not for example incorrect inactive so children as you can see that these words build up your vocabulary now instead of writing not correct or not active you can use words like incorrect inactive so such words improve the quality of your essays and your writing skills next we have again in and it means into for example inject inside next we have air and air means not for example irresponsible irrelevant so not responsible not relevant so if you add here to the root word or to the mean word a new word is formed and that is irresponsible irrelevant isn't it easy children next we have micro and micro means small for example microscope microfilm next we have mid and mid means middle i know you all know this for example midfielder midway next we have miss and it means wrongly for example misbehave misuse so children when we behave in a wrong manner or when we use things in a wrong way we can use words like misbehave misuse next we have non and non means without for example non-violent nonsense next we have post post means after for example post lunch postpone so instead of saying after you can use post next we have pre and pre means before prefix preschool so now instead of using before you can use pre next we have re and re means again for example reappear refill next we have semi semi means half for example semicircle semifinal next we have sub sub means under submerge subtitle next we have try and try means three for example triangle tricycle next we have on and un means not for example unable unfriendly so instead of writing not able not friendly you can use unable unfriendly and the last prefix is uni and it means one unicycle unicorn i hope children you have understood what are prefixes just go through the list carefully and learn the meaning of different prefixes and children learn the examples also and you can use different examples also now children let's discuss the exercise now instead of circle you will write underline the prefix in each of these words and write its meaning then give two more examples using the prefix so the first word is unicorn and you will underline uni uni means one and the examples are uniformity universal next is tricycle you will underline try try means three for example tripod triangle next is impolite you will underline m m means not and the examples are immature immovable now children cut the word integrate and instead of integrate we will use incorrect you will underline in in means not and the examples are incomplete invisible next we have 4c you will underline 4 4 means before for example foresight foremost next is non-fiction you will underline non non means without for example non-stop non-living next is descent and you will underline d d means away from examples are demotivate d value next is reappear you will underline re re means again examples are return rediscover next unhealthy you will underline an means not for example unknown unhappy next we have mispronounce you will underline miss miss means wrongly and the examples are mistake misunderstand next we have prepaid you will underline pre pre means before so the examples are prepare preview next we have disorder you will underline this dis means not and the examples are disapprove dislike now children you will be doing this exercise in your english language classwork copy you don't have to worry i will be posting the class for copy instructions separately so you only have to follow the instructions carefully okay
