The definition tag is used in situations where the question is either about how some term or concept is defined or where the validity of an answer depends on a subtle definition of some term or concept used in the question.
The definition tag is used in situations where the question is either about how some term or concept is defined or where the validity of an answer depends on a subtle definition of some term or concept used in the question. For example, current is defined as the flow of positive charge so a question about the direction of current or flow of electrons and why it's opposite would qualify for the tag.
