Synonym discussion
Sense: noun/5
All four terms describe someone who resembles another person closely, but they differ in intensity and connotation. 'Look-alike' is neutral and factual — it describes resemblance without any emotional weight. 'Ringer' (especially 'dead ringer') is informal and stronger, suggesting a resemblance so close that deception or confusion is possible; it implies the similarity is striking enough to fool people. 'Doppelgänger' carries a supernatural or eerie tone — it suggests an uncanny double that feels almost ghostly. 'Spitting image' is a colourful informal idiom with roughly the same force as 'dead ringer' but a warmer, more affectionate feel. For everyday conversation, 'look-alike' works best for mild resemblance; use 'ringer' or 'spitting image' when the similarity is remarkable. For example: 'My brother is my look-alike but not a dead ringer — we have different noses.'

Etymology
'Ringer' comes from the verb 'ring', referring to someone who rings a bell. The sports-cheating sense emerged in 19th-century horse racing: a fast horse was secretly 'rung in' (substituted) for a slower one, like a bell being 'rung in' to a performance. The look-alike sense grew from the idea of a substitute so convincing they could pass for someone else. The vehicle-fraud sense follows the same deception logic: a stolen car is given a fake identity, 'rung in' as a legitimate vehicle.
