Why Is There Confusion over the Plural of Echo?There is confusion because the rule for forming plurals with nouns ending in o isn't straightforward. Most nouns will just add an s. For example:
- Kangaroo becomes kangaroos.
- Piano becomes pianos.
- Embargo becomes embargoes.
- Torpedo becomes torpedoes.
- Volcano becomes volcanoes or volcanos.
- Halo becomes haloes or halos.
Though echos and echoes are both accepted plurals, echoes is by far the more common of the two. (See the difference in Google's Ngram Viewer.)
Don't Use an Apostrophe to Form a PluralAdding 's is never an option when forming the plural of a noun. Despite this simple rule, inexperienced writers often feel compelled to add an apostrophe, especially when the noun ends with a vowel (e.g., piano, tomato, emu). For example:
- The tomato's were ripe.
- The tomatoes were ripe.
