In-famously is an adverb often used to describe something that is done in a way that is widely known but very negative or shameful. Fortunately, there are several synonyms to this word which can be used to convey the same meaning in different ways. Infamously can be replaced with words like notorious, shamefully, disgracefully, nefariously, discreditably, and scandalously. These synonyms have different connotations which can be employed depending on the context of the sentence. For instance, disgracefully would be a fitting replacement when describing an action that is shameful but not necessarily illegal. The synonym notorious, on the other hand, would be appropriate for a situation where a person's actions have created a widely known bad reputation.
