The "ea"-digraph/"ea digraph/ea-digraph can be pronounced differently, which is not regulated.

Could you tell me which is orthographically correct?
1. The "ea"-digraph can be pronounced differently, which is not regulated.
2. The "ea" digraph can be pronounced differently, which is not regulated.
3. The ea-digraph can be pronounced differently, which is not regulated.
As far as I am concerned, the 3rd is correct.

Use the second one.

Use the second one.

Is it the most common?

Why only these three? Have you not considered any other options?

Please tell us what you're writing.

I think so.

I'd say;

The ea digraph can be pronounced in at least three different ways. There are no rules to help the learner choose.

What other options are there?

One clear way would be to use a different typeface, such as the italics used in post #6. Don't clutter with punctuation marks.

I think it's a considerable option to use single question marks in this case, right?
E.g.: 'ea' digraph, 'ow' letter combination, 'able' suffixed adjectives, 're' prefixed verb.

You mean 'single quotation marks'.
