Here's why:
* The "-ed" ending is usually part of the word. It signifies the past tense or past participle, and it's not a separate word.
* They usually have one primary stress. The stress is usually on the first syllable, making it a two-syllable word.
Example:
* "wanted" is a two-syllable word with the stress on the first syllable: WANT-ed. It doesn't break into three words.
However, there are exceptions:
* Some words can be hyphenated. For instance, "well-bred" is technically two words, but it's usually hyphenated to create a single unit.
* Phrases might involve a word ending in "-ed." A phrase like "looked up" has two words, but the first word does end in "-ed."
