While I am familiar with a pride of lions, a murder of crows, a herd of horses, a host of angels, a nest of vipers, a quiver of arrows, and a gaggle of geese, there are more that I was not familiar with, and are apropos or simply curious (understanding the etymology would be very helpful!) Here are a few of my favourites.
