Relubrication → It is formed from "re-" (meaning again) and "lubricare" (from Latin, meaning to make slippery or to lubricate) and "-tion" (meaning the action or process of). The word "relubrication" means the process of applying lubrication again.
Think of 'again' ('re-') making something 'slippery' ('lubricare') — that's why relubrication refers to the action of applying lubrication again.
