The adjective forming suffix " -y " also has several meanings:

1. 
   composed of, full of (bony, stony)
   
2. 
   characterized by (rainy, cloudy)
   
3. 
   having the character of resembling what the stem denotes (inky, bushy).
   

Thus, affixes have different characteristic features. The Comparative analysis of the English is not so rich in suffixes as, for example, the Uzbek language. The total number of suffixes is 6 7 in English, but the Uzbek suffixes are 171³ and vice versa, prefixation is more typical to the English language than Uzbek. In Uzbek there are following prefixes: бе -, но-, ба-, бо-, ним- . By their origin the Uzbek affixes like English ones are divided into native and borrowed.
The suffixes: -чи , -rap , -зор ,-ли , -лик , -ок are native suffixes , but: -изм , -ация , бо-, но-, нома-, -ки are of borrowed origin. The affixes may be divided into different semantic groups. These semantic groups of affixes mat be different in different languages. For example, diminutive affixes in Uzbek are more than in English.
DIMINUTIVE SUFFIXES
In English In Uzbek
-ie (birdie) -акай (йул-йулакай), -алак
-let (cloudlet) (дунгалак)
-ling (wordling) -жон (дадажон)
-ette (mountainette) -кач (тахтакач)
-ock (hillock) -кина (гудаккина)
-у (Jony) -ой (Салимаой)
-et (whippet) -ча (аравача)
-kin (tigerkin) -чак (тугунчак)
As compared with the Uzbek language the native affixes are more widely used in English.
In Uzbek : -сиз (кулсиз), бе- (берахм), но- (нохуш)
In English : -less , а- , an- (anomalous), un- (unkind), dis- (dislike), anti- (antibiotic), de- (decode), in- (innocent), ir- (irregular), im- (impossible), non- (nondeductive). Though the number of Uzbek prefixes are very few, they are capable of changing words from one part of speech into another.
Here are given some examples: адаб (от) - боадаб (сифат),
хосил (от) - cерхосил (сифат),
илхом (от) - ноилхом (сифат),
бахт (от) - бебахт (сифат),
ранг (от) - нимранг (сифат).
Non-productive affixes are those which are not used to form new words in Modern English.
For instance, -ard , -cy , -ive , -en , -dom , -ship , -ful, - en , -ify are not productive suffixes ; in(i), ir(im), mis-, dis- are non-productive prefixes. These affixes may occur in a great number of words but if they are not used to form new words in Modern English, they are not productive.Conclusion
Word-formation is the process of creating words from the material available in the language after certain structural and semantic formulas and patterns.
As a subject of study, word-formation is that branch of Lexicology which studies the patterns on which the English language builds words. Like another linguistic phenomenon word-formation may be studied synchronically and diachronically.
There are two principal types of word-formation in Modern English: word-derivation and word-composition. Within the types further distinction is made between various ways and means of word-formation.
Distinction is made by Productive and Non-Productive ways of word-formation.
In the practical analysis of derived words the following characteristics of derivational affixes (suffixes and prefixes) should be pointed out:

1. 
   The productivity of the affix (highly productive, semi- productive or non-productive).
   
2. 
   The part of speech the affix forms (nouns, adjectives, verbs etc.).
   

Affixation (prefixation and suffixation) is the formation of words by adding derivational affixes to primary stems. One distinguishes between derived words of different degrees of derivation.
Many of Modern English derivational affixes were at one time independent words. Others have always been known as suffixes or prefixes within the history of the English language.
As a summary to the study of affixation as a productive way of word-formation, which presents a certain interest both for theoretical investigation and for the practical language use.
