restoration

The word is typically used as an uncountable noun when referring to the general process of fixing something, but it can be countable when referring to specific projects (e.g., "several restorations"). When capitalized as "the Restoration," it specifically refers to a historical period, most commonly the return of the monarchy in 17th-century England. In medical or health contexts, it is often used formally to describe recovery. In casual conversation, people are more likely to use words like "recovery" or "healing" instead.
