Correct spelling

licence

Correct spelling, explanation: this word originates in Latin, licentia, which present participle form is licere (to be permitted). Old Anglo-French word licence meant simply liberty and permission. This etymology points to the correct spelling licence and proves that liscence is the wrong one. Note: This spelling only exists in British English (see: license).
