i am in focus now look at me mom i'm in
focus all right we're recording hi
everybody my name is alicia welcome back
to top words today we're going to talk
about 10 useful prefixes a prefix by the
way is like a small word a few letters
that we attach to the beginning of a
word to change the meaning of that word
let's go
re
the first prefix is re re r e re means
again so we see the word re in like redo
or replay or re-imagine or recreate for
example so it means to do the base word
again so whatever you see re in front of
um or not everything but
if you see re before a base word like
that it can mean to do that thing again
so in a sentence
i have to redo my homework
auntie
the next prefix is auntie aunty or you
might hear anti as well anti or anti
both are fine um but it means against or
in opposition to or like kind of the
opposite of something so against against
anti so we see this in like um
antifreeze or antisocial or
anti-inflammatory or antibiotics so they
all mean against something um so like
the word antifreeze for example means
like against freezing so it's a
it's
antifreeze is a product that prevents a
liquid from freezing for example an
antibiotic is a medicine that we take to
kill like bad microorganisms in our body
germs in other words so we see bio in
that word so relating to like biology
antisocial refers to someone who does
not like social situations they are
against social situations an
anti-inflammatory
another type of medicine
is against inflammation so inflammation
can mean like swelling or like turning
you red for example so anti means
against something we see anti before
words which mean like opposing or
against that thing in a sentence
my boss is anti overtime
dis
so the next prefix is dis dis so dis
essentially this means not so we see
this in words like disrespect or
disapprove or disconnect or like
disagree for example so these words all
mean not
plus the base word so like disagree for
example means to not agree or disconnect
means to not connect so something is not
connected to the other thing uh
disrespect means to not respect
something for example so dis means not
plus that base word in a sentence
a good editor should be disinterested
x
the next prefix is x x
x means former former so something that
was once true is not true anymore we see
this very commonly in relationships so
for example uh ex-husband ex-wife
ex-girlfriend ex-boyfriend ex-boss so
all of these mean my former something my
former boyfriend my former girlfriend my
former boss my former roommate for
example in a sentence the ex-ceo was in
the news this week
mid
the next prefix is mid mid so mid means
like in the middle of or during
something so we can see this in a word
like uh midnight or mid-summer for
example or mid-morning so meaning in the
middle of or roughly in the middle of
something during that time period
midnight means in the middle of the
night or mid-morning it's like in the
middle of the morning so all of these
refer to mid something we can also use
it for like an action like mid-meal for
example or she was a mid-presentation
when the phone rang for example so mid
means in the middle of something in a
sentence
i was mid-breakfast when i heard the
news
ill
the next one is ill ill
so ill means again not or it's like a
negative prefix it means
the base word but not that base word so
we see this in words like illogical or
illegible or illegal for example so
these all mean not plus the base word so
illogical means not logical uh ill
legible illegible means unable to read
legible means readable illegible means
cannot read that thing unable to read
that illegal means not legal in other
words so an action that is against the
law so ill means not in a sentence
highly illogical captain
that's a star trek reference
the next prefix is
also means not it means not words that
fit this pattern for example could be
impossible or
impeccable or improbable or imperfect
for example so again it means not so
imperfect means not perfect uh
impossible means not possible um so im
means not it means not in a sentence
this is impossible
in
the next prefix is in in so again in
also means not it's a negative prefix
that we use there are a lot of words
that start with this in meaning not so
like inconsiderate incapable
inconceivable
inappropriate so they all mean not plus
the base word
for example like the word inappropriate
means not appropriate so behavior that
is not appropriate in a certain
situation or incapable means not capable
someone cannot do something they are
expected to do
so in
means not plus our base meaning the
opposite then of that meaning in a
sentence
he's incapable of running the country
the next prefix is ear ear so the
pronunciation is ear even though it's ir
ear for example we see this in like
irresponsible or irredeemable or
irregular so again this means not
something so irresponsible means not
responsible irregular not regular
irredeemable is something that cannot be
made up we cannot redeem that thing so
ear is another negative prefix meaning
not or no in a sentence
your behavior was irresponsible
none
the next prefix is
non-non-n-o-n so n-o-n is a prefix again
it means not or against or like i
shouldn't say against so non also means
not something uh so for example we see
it in a word like nonsense or like
non-sequential or non-sequitur so these
are words that all mean like not
something so for example non-sense means
no sense essentially not sense uh
non-sequitur so sequitur the base there
is like think of the word sequence we
see that same sort of base in sequence
as we see in non-sequitur
and that actually comes from the latin
meaning like to follow something so it
non-sequitur means like it does not
follow so a non-sequitur means something
that just it's not part of the
conversation it's like a random comment
is a non-sequitur so it does not follow
non-sequitur is one so none means not or
no in a sentence
this is nonsense
okay so those are ten useful prefixes so
you'll notice that a lot of these
actually mean no or not
but that doesn't mean that we can just
mix and match these so we can't add like
uh
un to the word logical we can't say like
unlogical or maybe like dislogical for
example we always need to use the same
prefix with the same root word so please
be careful just because these prefixes
mean the same thing doesn't mean that we
can just pick and choose as we like so
it's still important to learn the
correct prefix and the words that it
regularly attaches to so please keep
this in mind as you study all right
those are 10 useful prefixes i hope that
