Focusing on the impact of language:
* The way we speak can influence how others perceive us, making language a powerful tool for shaping social interactions. (This sentence uses "making" to show the direct impact of language on social interactions.)
* Since language shapes our thoughts and understanding of the world, it is crucial to be aware of the biases that can be embedded within it. (This sentence uses "since" to explain why being aware of linguistic biases is important.)
