Keep in mind I am a beginner and am simplifying For this example let us take the sun and put him in Aquarius, so he has -5 essential dignity and lets make the sun the 7th lord (7th house Leo). So his quality of what he can give wont be great or would be challenging due to -5 essential dignity.
Now let's say the sun will have -7 accidental dignity, and 4 points of accidental dignity making a total of -3. I see accidental dignity as the opportunity for a planet to act and bring results- regardless of its quality (essential dignity). Keep in mind this is an example, not me currently looking at scores and making the perfect hypothetical chart.
So would this person have a very slim chance at marriage considering the 4 accidental points scored? And the marriage would be not so great. Due to the low dignities.
I know a -5 essential dignity planet with high accidental dignity can be very unpleasant or bring less desirable results. And a high essential dignity (+10 for example) planet with very little accidental dignity will have little chance to fulfill its job
Please go easy on me, I am a beginner and this a very simple example. MODS the example is just a hypothetical one, I am not trying to break rules as it is hypothetical placement
