Is the words good/bad opinion signal words. For example, the vegetables are good.
Yes. Good is a matter of taste.posted by Ms. Sue
However, they may be more than just opinion, if specific criteria are given for attaching these value labels. For example, something might be a "good buy," if it offers more of a product (of the same quality) for the same or lower price.
The value labels of "good" and "bad" give very little information — unless the specific criteria for the labels are given. The same occurs for other relative terms, such as "big," "heavy," "loud," "a lot" and others.
For example, what is "a lot" of milk? For a baby, 8 ounces might be "a lot." For a teenager, it might be a gallon, while for a grocer, it might be 100 gallons.
I hope this helps a little more. Thanks for asking.posted by PsyDAG
