"A wife or a husband is a spouse."

Translation: 아내 또는 남편은 배우자다.

[Marcella1407]

How is "배우자다" conjugated?

[Sophiafilm]

It's 배우자 + 이다 in written/plain form, remain as in its dictionary form when gets added to a consonant, but when it gets added to a vowel 이 can be omitted.
배우자 + 이다 = 배우자이다 or 배우자다 - both acceptable.
빵 + 이다 = 빵이다.

[jiraiya1601]

how come we don't have to conjugate the form dictionary form here and can add 다 straight away? is 이다 an exception ?

[Sophiafilm]

You don't have to add 다, or anything else, because adjectives in the Written form in Present tense remain the same as in a dictionary.
이다 and 있다 are also adjectives.

[JoesCathbert]

아내 또는 남편이 배우자입니다 why is this wrong? duo....

[Maddie488671]

Confused about the usage of 또 here?

[nleconte]

또는 here means "or".

It's different from 또 (again, once more).

[kimmksk]

또 is an adverb that means again.
또한 is an adverb that links two phrase or sentences. Sometimes it can be 'Plus, ...'

[VincentNig4]

I think the right adverb to mean "OR" is " 나/이나" or also " 하거나".
