<span>A qualified term is something that be true, assuming other conditions are also met. For example, the right to free speech is a qualified right. You do have a right to free speech, provided that you aren’t breaking any conditions such as slander, obscenity, or plagiarism.</span>
It is true, because some is not an absolute term. The distinction between absolute and qualified terms is about the purposes, where absolute shows limitations and restraint for the given topic. For example, <em>The stars can only be seen at nights</em> - It is an example of absolute quality. We have a strict restraint here that the stars can only be seen at night time. But <em>Some frog species only have one leg </em>is an example of qualified term - In this sentence we show that there are other species, as well which we are not discussing.
