Clarifying could should and would

I know there are several topics asking for clarification on could, should and would.However, does anyone have a table showing all personal pronouns with negatives and future tenses. Something like,

Dylwn i I should Ddylwn i ddim I shouldn’t
Dylet ti you should Ddylet ti ddim you shouldn’t


This I’m sure would help stop the confusion and anyone wanting clarification could be pointed to the table in the thread which would negate having to ask questions on each of the above, i.e. Could, should and would.

Hope this will help :slight_smile:image
