The statement that the verb 'going' has multiple meanings ranging from physical movement to future tense is a matter of basic linguistic description and everyday definition, requiring no formal citation.
The claim is trivially true by definition and everyday observation in English grammar and lexicography, fitting the criteria for common knowledge. None of the retrieved papers specifically target or test this standard lexical fact about the word 'going', though the papers generally discuss syntax, tense, and grammaticalization.
