Select the word that has nearly the same meaning as the given word: Idiosyncrasy

The word "idiosyncrasy" refers to a distinctive or peculiar feature or characteristic of an individual, particularly one that sets them apart from others. The correct choice, "peculiarity," closely aligns with this meaning, as it signifies an unusual trait or characteristic that distinguishes someone or something. Both terms suggest a uniqueness that can be observed in behavior, habits, or attributes.

In contrast, the other options represent different concepts. "Selfishness" refers to a lack of consideration for others, focusing more on one's own needs or desires, and does not capture the essence of individuality implied in "idiosyncrasy." "Depression" is a term related to a mental health condition characterized by persistent sadness and loss of interest, which is unrelated to the idea of unique traits. "Normality" denotes a state of being typical or standard, which is the opposite of the uniqueness conveyed by "idiosyncrasy." Therefore, "peculiarity" is the best synonym, as it encompasses the idea of an individualistic characteristic.
