What Is the Difference Between Online and On-line?

As time passes by, words evolve and change meaning. Words are adapted to fit with the times and get new meanings and new spellings. The word on-line originally was used to refer to a train being on its rails. This was used back in 1915 and it wasn’t till 1945 that it started to see other uses. 

As it changed and the internet was invented it shifted slowly from the hyphenated version on-line to online. In the 90’s it was still common to refer to the internet with the compound word on-line. There are still some uses today but the far more common spelling is online as a single word in the English usage.
