Negative Equation Construction: N(-이/가) 아니에요/아닙니다

Examples

(1)	김영미, 마이클 정, 샌디 왕은 한국어 학생이에요.
	김영미는 한국사람이에요. 마이클 정도 한국사람이에요.
	샌디 왕은 한국사람이 아니에요.
(2)	A:	IU 학생이에요?
	B:	저학생아니에요.
(3)	(A has called, and thinks that the one who answered the phone is 민호)
	A:	민호씨, 안녕하세요?
	B:	저 민호 아니에요. 마이클이에요.

-이에요/예요 and -입니다 specify a positive identification. When there is a reason to believe that the other party in conversation wrongly assumes something that it is not, the speaker may want to deny the assumption, and correct it. In this context, 아니에요 and 아 닙니다 are used, which are negation constructions of -이에요 and -입니다 respectively. They consist of the Negation marker 안 plus -이에요 or -입니다; that is,

안+이에요=아니에요
안+입니다=아닙니다

 In (1), the first two students in the Korean class are identified as Korean. This might trigger readers's expectation that 샌디왕, the third student, might be a Korean as well. In order to correct that assumption, the narrator gives a negative identification, and gives a correct information subsequently.

Note that in conversations as in (2) and (3), the particle -이/가 is not attached. The particle may be attached when the speaker feels that s/he needs to emphatically specify what assumption is denied, say, among a number of candidates.

In Conversation 2, 마이클 asks 샌디 if she is a Korean (샌디씨는한국사람이에요 ?). Here 마이클 is not assuming that 샌디 is a Korean, but is simply asking for a factual information. In this context, giving a negative identification is pragmatically not appropriate. 샌디 simply says 'yes' or 'no', and gives a factual information, namely, "아니요, 중국사람 이에요".
