Short answer: on flags, a star usually stands for unity, a state or province, or a guiding ideal; a sun for a new beginning, independence or energy; a crescent (often with a star) for Islam or Ottoman heritage; a cross for Christian heritage; and plants or animals for the land and its people. A symbol on a flag is called a charge, and its meaning is whatever the flag's designers officially say it is – the same star can mean different things on two flags.

Stars
The star is the most common symbol on national flags. Most flag stars have five points. Several stars often mean several parts of one whole: the 50 stars of the United States flag stand for its 50 states, and the stars of the Southern Cross on the flags of Australia and New Zealand place those countries in the southern sky. A single large star usually stands for unity or a guiding ideal. In the flag maker, the five-point and eight-point stars are the quickest way to add meaning without clutter.
Suns and discs
A sun usually means a new beginning, independence or the warmth of the people. The Sun of May on the flags of Argentina and Uruguay refers to the independence era; the eight rays of the sun on the Philippine flag stand for the first provinces that revolted against Spanish rule. A plain disc is also usually a celestial body: Japan's red disc is the sun, Bangladesh's red disc is the sun rising over Bengal, and the discs on the flags of Palau and Laos represent the moon.
Crescents
A crescent, often paired with a star, is widely associated with Islam and with the heritage of the Ottoman Empire – think of Turkey, Pakistan, Algeria and Tunisia. It is not always religious, though: on Singapore's flag the crescent stands for a young nation on the rise. If you use a crescent on a fictional flag, decide whether you want that real-world association.
Crosses
Crosses usually point to Christian heritage. The off-center Nordic cross, first used by Denmark, is shared by Sweden, Norway, Finland and Iceland, so it also signals Scandinavian ties. Switzerland uses a centered white cross on a square red flag, and Greece places a cross in its canton. A diagonal cross is called a saltire, as on Scotland's flag.
Plants, animals and landscapes
Natural symbols tie a flag to its land: Canada's maple leaf, Lebanon's cedar tree, Kiribati's waves under a rising sun. Animals stand for character or legend, like the dragons of Wales and Bhutan and the eagles of Mexico and Albania. Detailed animals are hard to draw and reproduce, which is one reason most flags prefer simple geometric symbols.
Shapes: triangles, diamonds and shields
Geometric shapes carry meaning too. The white triangle of the Philippine flag stands for liberty, equality and fraternity; a hoist triangle, as on the flags of the Czech Republic and Cuba, adds forward movement. Brazil's yellow diamond frames its starry globe. Kenya's Maasai shield and spears stand for defending freedom.
How to choose a symbol for your own flag
- Pick one idea. One symbol that means one thing reads better than three that mean many things.
- Check real-world associations. A crescent, a cross or a red star carries strong existing meanings; use them on purpose.
- Keep it simple. A symbol should still be recognizable when the flag is 60px wide, which is why simple stars and suns beat detailed emblems.
- Write the meaning down. One sentence per symbol and color – this is what turns a picture into a flag.

Summary
Stars usually mean unity or regions, suns mean a new beginning or independence, crescents usually mean Islam or Ottoman heritage, crosses mean Christian or Scandinavian heritage, and plants and animals mean the land and its people. On any real flag, the official explanation is what counts, and on your own flag, the meaning is the one you write down.
