This template removes the last word of the first parameter, i.e. the last non-space token after the last space. Use |1= for the first parameter if the string may contain an equals sign (=). By default, words are delimited by spaces, but the optional parameter |sep= can set the separator to any character.
Regular expressions (or regex) are a common and very versatile programming technique for manipulating strings. On Wikipedia you can use a limited version of regex called a Lua pattern to select and modify bits of text from a string. The pattern is a piece of code describing what you are looking for in the string.
