Poignancy and nostalgia are not typically considered to be opposites because they have different connotations and associations. Poignancy is often used to describe an emotional feeling of sadness or sorrow that is evoked by a particular experience or memory, whereas nostalgia is a longing for a past time or place, often with a sense of sentimentality or yearning. While these two emotions can sometimes overlap, they are distinct in nature and can be experienced independently of each other.
