View source for 아/어/여 + 요

The '''A/V + 아/어/여''' form is probably the most important form to learn in Korean and is probably the most frequently used grammar pattern since it can be used as informal polite and informal friendly style amongst friends and people of equal or lower status (by dropping the 요 at the end). Also many other grammar patterns depend on the basic conjugation rules of this pattern to form other grammar patters, see [[:Category:아/어/여 form]] for other patterns.

<!--Can also be a command-->
==Usages==
This basic pattern is probably the most common major grammar pattern in Korean. Not adding a 요 is very informal and called [[반말]], which should only be used with friends, and people that are younger than you and people who are in lower position than you (depends on the situation, so not always). '''(1)''' It is used for making informal present tense sentences, adding to the end 요 makes it become the informal polite form. '''(2)''' This pattern can also be used to issue a command, similar to [[V + 아/어 + 라]].

==Sentence Examples==
As informal/informal polite present tense:
{{Example table
|Korex1 = 집에 가요?

==Conjugation Rule==
There are three types of basic conjugation rules, the first two depend on whether or not a 오 or 아 verb appear in the last syllable of the adj/verb stem. The last rule is simply used for 하다 verbs.

===Verb/Adj Stem + 아===
*If the last syllable of the stem contains the vowels ㅗ or ㅏ, then 아 is added. If it is a stem with no [[받침]] like 가다, then an extra 아 isn't added. 
*Please note '''this rule does not apply for 하다 verbs''', see the [[A/V + 아/어/여 + 요#여 Verbs/Adjectives (하다)|section below]] for 하다 adj/verbs.
*Stems that end in 오 are often contracted to 와 (오 + 아 = 와), especially in colloquial speech. 
*Irregular verbs do exist, see the [[A/V + 아/어/여 + 요#Irregular Forms|irregular verbs section]] below for more details.

|}

===Verb/Adj Stem + 어===
*If the last syllable of the stem contains any vowel other than 오, 아, and is not a 하다 verb then it becomes an 어. Note that verb stems with 이 turn into a 여(see next section), it is due to a contraction of 이 + 어 = 여. 
*If the last syllable of the stem contains the vowel 이 and there's no [[받침]], i.e. 시키다, then it becomes a 여 (시켜). The 여 is a result of the contraction between 이 + 어. The contracted form is almost always used in spoken and written Korean. Also note a seperate table of examples has been created below for the adj/verb stems which end in 이.
*Irregular verbs do exist, see the [[A/V + 아/어/여 + 요#Irregular Forms|irregular verbs section]] below for more details.

===여 Verbs/Adjectives (하다)===
*Any verb or adjective that ends in 하다 falls under this category. 
*The 하 becomes 해 due to a contraction with 하 and 여. 
*The contracted form is used most of the time, especially in colloquial speech. However, 하여 is used mostly in very formal situations.
