What is another way how to spell ed?

There isn't really another way to spell "ed" that retains its pronunciation and meaning as a past tense or past participle ending in English.

However, depending on the context, you might be looking for:

* Different spellings of words that end in "ed": For example, "said" could be spelled "sed" or "sayd" in older texts, but these are now considered archaic spellings.

* Alternative word endings that convey a similar meaning: For example, instead of "walked," you could say "went for a walk" or "took a stroll."

If you could provide more context about what you're trying to achieve, I might be able to give you a more specific answer.
