What is the meaning of the word 'peculiar'?

The word 'peculiar' primarily refers to something that is distinctive or characteristic, often implying that it is strange or unconventional. In this context, 'unusual' accurately captures the essence of 'peculiar', as it indicates something that deviates from the norm or is not typical in nature. It is important to recognize that while 'peculiar' can sometimes carry a negative implication, it fundamentally denotes that something stands out due to its differences or oddities.

On the other hand, the other choices—common, ordinary, and standard—suggest a sense of familiarity or regularity, which is the antithesis of 'peculiar'. These words describe things that are widely accepted or typical, rather than highlighting the uniqueness or strangeness that 'peculiar' embodies. Therefore, 'unusual' fits perfectly as it reflects the distinctiveness implied by the word 'peculiar'.
