I&#x27;m Not Joking, This Plurals Quiz Is Actually Really Challenging

_Fish_ and _fishes_ are [both](https://www.merriam-webster.com/dictionary/fishes) generally accepted as the plural form of _fish_.

Yep! As weird as it may sound, [culs-de-sac](https://www.merriam-webster.com/dictionary/cul-de-sac) is the right plural. Cul-de-sacs is also correct.

_Octopi_ is often [mistaken](https://en.oxforddictionaries.com/explore/what-are-the-plurals-of-octopus-hippopotamus-syllabus) as the plural of _octopus_ and is even listed in some dictionaries. But because the word is [originally](https://www.buzzfeed.com/clairedelouraille/octopuses-vs-octopodes-vs-octopi?utm_term=.pba0AkZjqd#.hnRKLp1w0M) Greek and not Latin, the \*more\* correct forms are _octopods_/_octopodes_ and _octopuses_.

Octopi!

The [plural](https://www.merriam-webster.com/dictionary/moose) of _moose_ is just _moose_! Nothing changes. _Deer_ and _sheep_ are two other words that don't change in their plural forms.

[_Media_](https://www.merriam-webster.com/dictionary/medium) is the plural of _medium_, and _mediae_ is the [plural](https://www.merriam-webster.com/dictionary/media) of _media_!

Beefs and beeves are [both](https://www.merriam-webster.com/dictionary/beef) acceptable plurals of the word; _beef_ is strictly singular.

Beef!

_Opera_ is already plural! _Opus_ is the [singular](https://www.merriam-webster.com/dictionary/opus) form. Who'd a thunk?

False!

_Indexes_ and _indices_ are [both](https://www.merriam-webster.com/dictionary/index) correct plurals of _index_!

_Lasagne_ is [also](https://www.merriam-webster.com/dictionary/lasagnas) a correct plural.
