/ˈdia/

In many Spanish-speaking cultures, the greeting buenos días is used in the plural. While English says 'good morning' in the singular, Spanish treats the morning as a collection of days.
While English 'day' and Spanish día look similar, they actually come from completely different roots. The Spanish word is a descendant of a Proto-Indo-European word meaning 'sky' or 'heaven'.
In some Spanish dialects, particularly in parts of the Caribbean, the pronunciation of the 'd' in día can be very soft, almost disappearing between vowels.
