Final answer:
The speaker's discussion about child-rearing practices and language addresses the adaptation of language to evolving societal norms and research, challenging traditional gendered speech patterns and suggesting that language in parenting is subject to change.
Step-by-step explanation:
The speaker's discussion of changing the way children are raised implicitly addresses issues of old terms and evolving language terminology by suggesting that rearing practices influence the development of gendered speech patterns. This implicates that such patterns are cultural and hence subject to change, which can be reflected in the language used in parenting. By introducing new and evolving terminology related to childcare and questioning traditional perceptions, the text shows an intent to adapt to societal shifts, indicating that the language we use regarding child-rearing is neither static nor immune to the transformation that comes with new research and societal evolution.
The linguistic research mentioned underpins the idea that social and cultural factors play a substantial role in language development and acquisition, further reinforced by examining the relationship between language and power, and how it is used to structure gender, race, and ethnic dynamics. Therefore, by challenging the notion that language and its associated roles are predetermined and unchangeable, the speaker's discussion aligns with the idea that language is integral to culture and can be retooled to meet the needs of an evolving society.
