Don't think too hard. You need lots of context: Mostly that a sequence of two statements in a procedural language like C (where these are separated by semicolons) means to "execute the statements and realize their effects one after another". And then maybe you should know Monads as used in Haskell (you could say monads generalize the semicolon to include other meanings such as "can fail", "can have multiple results", "can do IO" etc).
