"Later" vs "later on." [duplicate]

What's the difference between the two?

Later the doctors found out that my case was a bit different.

Later on the doctors found out that my case was a bit different.

Is one more common than the other?


Solution 1:

"later" and "later on" have the same meaning. Sometimes "later on" is preferred because it has another, smoother rhythmical flow. You can consider "later on" as just a variant for "later".

Solution 2:

  1. "Later" is definitely more formal than "Later on"
  2. According to me the "on" is just a filler to make the sentence smoother.

    For Example- Many times we use "in order to", even though "to" is sufficient.

Solution 3:

"Later on" is more informal than just plain "later."
