The word 'trill' is a musical term used to describe a particular sound made by a singer or an instrument. It is used in the context of music, especially in opera or classical music, when a singer or an instrument rapidly alternates between two notes. It is also used in birdwatching, to describe the high-pitched, rapid chirping sound made by certain birds. In everyday conversation, 'trill' is less common but can be used to describe something that is very exciting or enjoyable.
