The word "这么" is formed by combining the demonstrative pronoun "这" (zhè), meaning "this", with the ancient and functionally generic suffix "么" (me), which serves to nominalize or substantivize the concept. This fusion creates a single demonstrative adverb that literally and conceptually points to "this kind of" or "in this way", where "么" generalizes the demonstrative force of "这" away from a specific object to instead modify the manner, degree, or type of an associated action or quality.
