When it comes to expressing the idea of not giving much importance to something, there is a range of synonyms that can be used to convey this message. Instead of the phrase "attached little importance to," one could use words like "disregarded," "neglected," "devalued," "minimized," "downplayed," or "undervalued." These synonyms can be used interchangeably depending on the context in which they are used. For instance, if you want to downplay someone's concern, you could say that you've "minimized" their worries. Conversely, if you want to dismiss something that's valuable, you could say that it's been "neglected." By using synonyms effectively, writers can add depth and variety to their writing, while effectively conveying their intended meaning.
