A speaker’s accidental slip of the tongue primarily illustrates which linguistic concept?

💡 Explanation:

A 'slip of the tongue' or speech error is an imperfection in the actual production of language, which Noam Chomsky termed 'Linguistic Performance.' Performance refers to the actual use of language in concrete situations. The speaker's underlying, abstract knowledge of the language rules, which is unaffected by the error, is termed 'Linguistic Competence.'
