Synonym discussion
Sense: adjective/1
All four words describe something outside what is normal, but they differ in strength and tone. 'Strange' is the most neutral and general — it covers anything unusual, surprising, or unfamiliar. 'Odd' is slightly weaker and very common in conversation, often suggesting something is a little off but not alarming. 'Weird' is more informal and stronger, implying something unnatural or unsettling. 'Peculiar' adds a tone of curiosity or suspicion — something that seems specifically unusual in a noticeable way. 'Bizarre' is the strongest, describing something extremely unusual that is hard to believe or understand. For example, a 'strange noise' might just be unexpected, while a 'bizarre noise' would be deeply puzzling. A 'peculiar smell' draws your attention, but a 'weird smell' might make you feel uneasy.

Etymology
The word 'strange' entered English through Old French 'estrange', which came from Latin 'extraneus' meaning 'external, foreign, not belonging'. The Latin root 'extra' means 'outside'. This explains why 'strange' carries meanings of both 'unusual' (outside the normal) and 'foreign' (outside one's own country). The sense of 'unfamiliar' developed in the 13th century, and the modern sense of 'odd or surprising' became common by the 16th century.
