Investigation (part of speech)
The survey is one of the parts of speech, attached to the cognition, to make a relationship with other words or add a special meaning. Typically, there are 'to', 'to', and 'to'. Research is one of grammatical morphemes because it has no practical meaning. In Korean grammar, a relative word or a jirim indicates an investigation. The survey is largely divided into questionnaire, assistant, and connection survey.
