I live in Malaysia, and we use British English in as our second language. But if you work in computer-related field or watched too many hollywood stuff, you may encounter spelling differences between American English and British English.
Most notably is : “program” is actually “programme” in British English. “dialog” is “dialogue”, “argument” is “arguement”
analyze = analyse
critized = critised
color = colour
favorite = favourite
rooster = cock (hehe, ok i’m getting tired of this)
