Why Is There Confusion over the Plural of Domino?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.
- Tomato becomes tomatoes.
- Potato becomes potatoes.
- Flamingo becomes flamingoes or flamingos.
- Echo becomes echoes or echos.
Though dominos and dominoes are both accepted plurals, dominoes is 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 piano's were expensive.
- The pianos were expensive.
