The verb corresponding to blasphemy—which means a contemptuous or profane act or utterance against God or another sacred entity—is blaspheme. Its pronunciation (blas-FEEM) can be a little awkward for English speakers as we’re not used to iambic verbs, and this might partially explain why the more natural-sounding blasphemy sometimes appears as a verb, especially in speech.
Examples
Blasphemy is about ten times as common as blaspheme, but the verb can be useful. For example, these writers use blaspheme and its derivatives blasphemed and blaspheming well:
