I made a flag for the Igbo language. The four crosses represent speech from nsibidi motifs, they are four representing Igbo spoken on all four corners of the world/universe. The third raised cross represents the individual and in extension individual/unique dialects of Igbo. The green represent life and posterity, and also symbolic of the colour of omu (tender palm fronds), therefore sacredness, as in, upholding the language. The white represents neutrality and community.
I'm thinking this could be the flag an Igbo language academy down the road. I generally see the Igbo language as separate from ethnic alliances or politics. Ratio is 1:2.
