Ludwig's WRAP-UP
The phrase "slowly deteriorating" effectively communicates a gradual decline in condition or quality. Grammatically, it’s sound, with the adverb 'slowly' modifying the verb 'deteriorating'. Ludwig confirms that it commonly appears in news, media, and scientific contexts, as an indicator for a process in which something gradually worsens.
While versatile, it's important to use it precisely. It should not be used if the condition remains the same and not worsens, in those cases, "not improving" can be a better alternative, depending on the context. Other alternatives, like "gradually declining" or "progressively worsening", can add nuance to your writing. The key is to ensure your word choice accurately reflects the pace and nature of the decline you're describing.
