What does relentless mean?
Relentless describes an action, pressure, or effort that continues persistently without pause, weakening, or mercy. In its most common use, the word conveys the force of an advance or demand that cannot be stopped: relentless pressure, opposition, or pursuit. It can also describe a person who keeps pursuing a goal despite difficulty, although the adjective often carries a critical or negative tone when the persistence is unyielding, exhausting, or indifferent to other people. Because relentless combines the idea of striving with the sense of refusing to relent, it intensifies both endurance and harshness. It is equally natural in British and American English, though the choice between relentless, unrelenting, and inexorable depends on context. Unrelenting often emphasizes an uninterrupted course, while inexorable more strongly suggests a process that cannot be turned back. Relentless is useful when persistence itself is central, especially where the consequences of that persistence matter.

Where does relentless come from?
Relentless appeared in English in the early 17th century. It was formed from relent, meaning to become less forceful or to yield, together with the suffix -less, and ultimately draws on Latin lentus, meaning flexible, slow, or sluggish through Medieval Latin relentare and French relentir. The same Latin root underlies words such as lent and the musical marking lento, while relent and relenting preserve the central idea of easing pressure or giving way.
