Flag signals can mean any of various methods of using flags or pennants to send signals. Flags may have individual significance as signals, or two or more flags may be manipulated so that their relative positions convey symbols. Flag signals allowed communication at a distance before the invention of radio and are still used especially in connection with ships.

Famous quotes containing the words flag and/or signals:
“Hath not the morning dawned with added light?
And shall not evening call another star
Out of the infinite regions of the night,
To mark this day in Heaven? At last, we are
A nation among nations; and the world
Shall soon behold in many a distant port
Another flag unfurled!”
—Henry Timrod (1828–1867)
“The term preschooler signals another change in our expectations of children. While toddler refers to physical development, preschooler refers to a social and intellectual activity: going to school. That shift in emphasis is tremendously important, for it is at this age that we think of children as social creatures who can begin to solve problems.”
—Lawrence Kutner (20th century)
