hello and welcome to prefixes in this video you'll learn about a special group
of letters that appear at the beginning of words we don't know the meaning of a
word we sometimes ask our parents or check the dictionary for help I'll show
you a trick to figure out the meaning of words without having to ask anyone the
trick is using prefixes as clues what is a prefix a prefix is a group of letters
at the beginning of words that have a specific meaning when a prefix is added
to a word it creates a new meaning of the word pre is a Latin word that means
before fix means to attach we are attaching a set of letters before a word
let's take a look at how you can use them to help you understand the meaning
of words the prefix re is very common it means again example where this prefixes
use are reread rewrite and review do you see read this is the root word because
it's the main word knowingly means again what do you think reread means if you
guess that it means read again then you are correct what about the next word
rewrite here the root word is write if re means again
what does rewrite mean yes it means to write again the final word is review
what is the root word yes view is the main word or root word and re is the
prefix if read means again then what does review mean right it means to view
again or to look over another time let's move to another prefix un means
not or the opposite of examples are unhappy untie and unlucky the root word
is happy and the prefixes unmeaning the opposite of what does unhappy mean
that's right an unhappy person is not a happy one the next word is untie if the
root word is tie and the prefixes on meaning the opposite of then what does
untie mean you guessed again if your mom asks you to untie your shoes she is not
asking you to lace them but to undo them let's take a look at the last word
unlucky the root word is lucky and the prefixes unmeaning not or the opposite
of what does it mean to be unlucky it means to not be lucky
the final prefix we are going to look at is dis this means not or opposite just
like the prefix um an example is dislike if the root word is like and the prefix
is dis meaning the opposite of then dislike must mean to not like something
good the next word is disappear if the root word is a peer and the prefix is
dis meaning the opposite of the disappear
must mean to make something not appear or to vanish Wow a prefix can make
something vanish the last word we are going to look at is disagree if the root
word is agree and the prefix is dis meaning the opposite of or not then if
you disagree with someone than you do not agree or do not like what they are
thinking or saying did you notice that prefixes change the
meaning of root words each time as you read pay attention to root words and
their prefixes then ask yourself what the prefix means and how it changes the
root word this will help you understand the meaning of the entire word you can
find lists of prefixes in the dictionary or online by the way did you see how
prefix has a prefix in it pre you can keep practicing phonics on our fun games
and until next time always be clever
