There are absolutely offensive words and absolutely non-offensive words. However, certain words exist on a continuum and their connotations resist easy classification. For instance, the update to Merriam-Webster's definition of "sexual preference" in 2020 sparked controversy on social media. The dictionary included a note that the term is widely considered offensive because it suggests that sexual orientation is a matter of choice.
The issue may be further complicated by factors such as reclamation, euphemism treadmills, implicit biases, internalized discrimination and dog whistle politics.
Therefore, an objective measure of offensivenss of words is beneficial for public discussion and can help in assessing the connotations of words over time. Is there any known measure ready to be applied to various contexts?
