racial terminology
A person’s race should only be included if relevant to the story. The words black and Asian should not be used as nouns, but as adjectives: black people rather than “blacks”, an Asian woman rather than “an Asian”, etc.
Say African-Caribbean rather than Afro-Caribbean.
Use the word “immigrant” with great care, not only because it is often incorrectly used to describe people who were born in Britain, but also because it has been used negatively for so many years. If relevant, say people are “children of immigrants”, not “second-generation immigrants”
rack or wrack?
You rack your brains, face rack and ruin, and are racked with guilt, shame or pain; wrack is seaweed
