Synonym discussion
Sense: adjective/1
All four words describe something that continues for a very long time, but they differ in tone and typical use. 'Eternal' is the most formal and often carries religious or philosophical weight — it suggests existence outside time itself, as in 'eternal life' or 'eternal truth'. 'Perpetual' emphasises uninterrupted continuity and is common for ongoing states or problems: 'perpetual motion', 'perpetual worry'. 'Endless' is more informal and can be positive or negative depending on context — 'endless possibilities' sounds hopeful, while 'endless meetings' sounds frustrating. 'Undying' is used almost exclusively with emotions and personal qualities, such as 'undying love' or 'undying gratitude'. If you want to describe a relationship that will never fade, 'everlasting' and 'undying' both work, but 'everlasting' is broader — it can apply to objects, memories, and abstract concepts, while 'undying' is largely limited to feelings.
Etymology
Formed in Middle English by combining 'ever' (meaning always, at all times) with 'lasting' (enduring, continuing). The word has been used since the 1300s to describe things that never end. The noun use meaning 'eternity' appeared in religious writings around the same period. The botanical sense — referring to plants whose flowers keep their shape when dried — emerged in the 1600s, reflecting the idea that these flowers 'last forever' after being cut.
