00:0-1	Yeah . Welcome to this lesson . Just a warning
00:12	. This lesson is going to be a little academic
00:16	. It is intended for high intermediate to advanced students
00:21	. This lesson will give you the tools you need
00:25	to take 2000 words and turn them into more than
00:29	15,000 words . Trust me I did it in university
00:36	actually . This is the first in a series of
00:39	lessons in which you will learn how to create new
00:43	words and understand words that you have never seen before
00:48	. After this lesson you will know how to describe
00:51	the structure of a word and you will have the
00:54	vocabulary that you need to take yours to the next
00:58	level . We will cover the terms morphine route ,
01:04	affix prefix , suffix , grammatical suffix , derivation ,
01:11	all suffix and word family . The first word will
01:16	cover is morphine . This is a word that is
01:20	used in linguistics . It is used to describe a
01:24	group of sounds that is meaningful . For example the
01:29	word morphine has to morph teams in it , morph
01:34	and m morph means shape and M means meaningful .
01:41	We know that they are separate meaningful units because they
01:46	can be added to different words while having the same
01:51	meaning . For example , morph is used in the
01:55	words polymorphic if an organism that can take many forms
02:01	metamorphosis , the process of changing form or shape morphology
02:09	. The study of morphine zones morph , this is
02:13	a verb that means to change shape , morpho ,
02:17	genesis , the origin and development of biological forms etcetera
02:25	. The list goes on . Mm is a technical
02:29	morphine . It is only used in linguistics . One
02:33	of the words that uses it is phone name ,
02:36	phone means sound and M means meaningful . So a
02:43	phoneme is a meaningful sound . In a language all
02:49	words are made of morphine zones . English uses two
02:53	types of morphine roots and affixes roots can exist independently
03:00	. They do not need to be added to anything
03:03	else to be used in a sentence . For example
03:07	eat . If you try to separate E . Or
03:11	to , they have no meaning on their own .
03:15	Therefore eat is a root . There are two types
03:22	of a fixes , prefixes and suffixes , prefixes are
03:29	added to the beginning of a root . A suffix
03:32	is added to the end . It is possible to
03:36	have several affixes added to one root . For example
03:41	, the latin root , sieve or service means citizen
03:47	, a person who is a member of a state
03:50	. Many routes can be added on to it .
03:53	For example , ill this gives us the word civil
03:57	. It has three meanings . One is belonging to
04:01	the affairs of a people of a state , for
04:04	example , civil law . These are the laws that
04:08	govern citizens as opposed to members of the military .
04:12	It can also mean polite . If we had the
04:16	prefix un to create the word uncivil , this means
04:21	not polite . We could say his behavior was truly
04:25	uncivil . With the word civil , you could add
04:29	the word eyes meaning to make or become and create
04:35	the word civilized , which means to make more culturally
04:39	advanced , adding the Suffolk's E . D . To
04:43	. This creates the word civilised meaning . Being in
04:48	a culturally advanced state and uncivilized means not being culturally
04:54	advanced and it goes on . We could create many
04:58	more words . The point is that one route can
05:02	take many affixes and suffixes can be added to other
05:07	suffixes to create even more words . Let's slow down
05:12	for a minute . There are actually two kinds of
05:16	Suffolk's grammatical and derivation . All first we'll look at
05:22	grammatical suffixes . Grammatical suffixes do not change the class
05:28	of a word , so they will not change a
05:30	verb to an adjective or a verb to announce .
05:34	They simply add grammatical information . A few examples are
05:41	the plural . S . one Banana , 2 Bananas
05:47	, the possessive s john's bananas , the third person
05:53	s john eats bananas . These are not all of
05:57	the grammatical suffixes , but I hope it's enough to
06:00	give you an idea of what they are . Do
06:03	not change the class of a word derivation all suffixes
06:08	do . For example , the adjective , quick can
06:12	have L . Y . Added to it to create
06:15	the adverb quickly . Here are two example sentences he
06:21	had a quick snack , that's an adjective , he
06:25	ate it quickly . That's an adverb . Learning how
06:29	to use these derivation . All suffixes is one of
06:32	the keys to speaking english fluently . Before we finish
06:37	, there is one more important idea for us to
06:40	look at and that is the word family . A
06:44	word family is all of the words that can be
06:47	made from a single root . Take a look at
06:51	this verb expect . We can make the noun expectation
06:57	. We could also make an adjective expectant or the
07:02	adverb expectantly . Here's another fun verb explode . We
07:09	could make the noun explosion and the adjectives exploded ,
07:16	explosive and explode . Herbal . There is also an
07:20	adverb explosively . Let's take a look at the noun
07:24	shape . There's also a verb shape . This means
07:30	to give shape to something . There are other now
07:34	owns shaper , shapely nous and shapeless nous . Then
07:41	we have the adjectives shape a ble shaped shapely and
07:49	shapeless . Here's a quick summary of what we've learned
07:54	in this lesson . You've learned about morphine , which
07:58	are a meaningful group of sounds . We've also looked
08:04	at two types of morphine . In english the root
08:08	and the affix . There are two types of affixes
08:13	, prefixes and suffixes , prefixes are added to the
08:19	beginning of a word and suffixes are added to the
08:22	end . Again , there are two types of Suffolk's
08:27	grammatical and derivation . All grammatical affixes do not change
08:33	the class of a word derivation . All suffixes ,
08:37	on the other hand , do change the words class
08:42	. Finally , all the different words that can be
08:44	created by adding a fixes to a route are called
08:48	a word family , mastering word families is one of
08:53	the keys to english fluency . Well that's it ,
08:57	folks have a great day .
