What Is The Plural Of Pesto?

Scrabble letter s

Short answer
Scrabble is the font of all knowledge when it comes to determining the validity of words, and current rules state that "pesto" and "pestos" are fine to use, whilst "pestoes" and "pesti" are not. On this basis, we think it's an open and shut case that "pestos" is the correct plural form of "pesto".

Long answer
For most nouns, simply adding an "s" onto the end turns it from singular to plural. This is the case for lots of foods, including those ending in "o"... pomelos, avocados and burritos to name a few. That's why most people use the word "pestos" when referring to more than one pesto sauce.

As is the case throughout the English language though, there are plenty of exceptions. The singular forms of mangoes, tomatoes and potatoes also end in "o" but utilise an "es" to pluralist the word. Does that mean that it's reasonable to use the word "pestoes" when referring to multiple pesto sauces?

Possibly, but to our eyes that word just looks weird which explains why some companies have invented their own name for multiple pesto sauces. Sacla for example, uses "pesti" when talking about their pesto portfolio.

There's even a fourth possibility, and that's to use the word "pesto" to describe the sauce in both singular and plural form. After all, we already do this with "fish", "flour" and "fruit", so why not "pesto" too?

Whenever we're faced with this kind of conundrum, we turn to the ultimate word checker... Scrabble. As it turns out, "pesto" and "pestos" are both allowed words, whilst "pestoes" and "pesti" are not.

Scrabble's rules are in a constant state of flux due to the hundreds of new words that are invented each year, but for the time being we will continue to use the word "pestos" whenever talking about pesto in the plural sense.

Overrule this logic as much as you see fit. All we ask is that you don't use "pesto's" when trying to talk about the sauce in the plural sense. That's a hate-crime against language and just won't do.
