“Programme” and “program” are two different spellings of the same word, which means a plan, schedule, or set of instructions. The spelling difference between the two is primarily a matter of geographic and stylistic variation.
In British English, “programme” is the preferred spelling, while in American English, “program” is more commonly used. However, there are some exceptions where “programme” is used in American English, such as in the context of arts and entertainment.
In general, “programme” is often seen as more formal or traditional, while “program” is considered more modern or informal. However, there is no hard and fast rule about which spelling to use, and both are considered correct and widely used in their respective regions.
