Ellipsis is the omission of words or phrases that are understood from the context. In the case of "if process omitted", the phrase "if the process is omitted" is implied but not explicitly stated.
For example:
* "If the process is omitted, the results will be inaccurate." (Full sentence)
* "Process omitted, results inaccurate." (With ellipsis)
Here, "if the process is omitted" is omitted, but it is understood from the context.
Therefore, "if process omitted" is an example of ellipsis.
