The phrase "for that matter" is an idiomatic expression that is typically used to introduce a new related idea or to emphasize a statement that has just been made. It is often used in spoken language and informal writing.
When used to introduce a new idea, "for that matter" is a way to suggest that the same principle or condition applies to a broader category or a similar situation. For example, if someone says, "I don't like pineapple pizza," another person might respond with, "I don't like any fruit on pizza, for that matter," implying that they dislike all types of fruit as toppings.
In terms of emphasizing a statement, "for that matter" is used to highlight that the previous statement holds true for a specific item, person, or situation. It reinforces the original statement and implies that the same applies to other things or circumstances. For instance, if someone states, "She doesn't eat gluten," another person might add, "I don't eat gluten either, for that matter," emphasizing their similarities in dietary restrictions.
Overall, "for that matter" serves as a connector or intensifier, linking a statement to something related or reinforcing an idea that has just been expressed. It aids in expanding the scope or emphasizing the validity of the original statement.
