Let’s delve into the realm of names.

In the English language, a horse is simply referred to as a horse,

Of course, without any discourse.

In Latin, a horse is called an “equus.”

Around 300 years ago, there was a man named Carl,

Who grew tired of the confusion caused by different names.

He would mention a particular flower, only to hear others say,

“Wait, you call that a rose? We call it by another name!”

Frustrated by this, he dedicated his life’s work

To naming everything in the world, both large and small,

Animals, plants, minerals—he had no limits at all.

Carl was quite an eccentric soul,

Known as Carl Linnaeus, he took on this extraordinary role.

Hailing from Sweden, his fondness for Latin was profound,

Even his own name, he wrote in Latin, Carolus Linnæus, renowned.

So, when it came to naming everything, he chose Latin as his tool,

A dog became “Canis,” a cat “Felis,” and a horse “Equus,” so cool.

Yet, Carl felt these names were too broad,

So he added a second word to make them more awed.

The dog became “Canis familiaris,” the cat “Felis catus,” in a niche,

And the horse was named “Equus ferus,” a more specific pitch.

He didn’t stop there, for he grouped them into families grand,

Taking the generic name of the best-known animal, so grand.

Adding “-ine” to the end, he formed the families’ names with flair,

Thus emerged canines, felines, and equines, a linguistic affair.

The actual family names in Latin ended in “-ae,” as it is known,

Though many have now changed as his system has grown.

Hence, if something is related to an animal in any way,

We use the Latin word as an adjective, without delay.

Not always scientifically, but descriptively, you see,

Like calling a donkey “equine,” or describing strength with glee.

Now, let’s explore some Latin adjectives for animals,

As we unravel their linguistic rituals:

Pig, known as “Sus domesticus,” is called swine,

A slight variation of the word “suine.”

Cattle, named “Bos taurus,” are referred to as bovine,

A fitting adjective for this majestic line.

The wolf, “Canis lupis,” is associated with “lupine,”

Describing its nature in a way that’s divine.

Foxes, “Vulpes vulpes,” possess a quality so fine,

Earning the adjective “vulpine,” truly benign.

Lastly, weasels, of the Mustela species, define,

Their descriptor is “musteline,” an adjective that’s fine.

So, there you have it, a glimpse into the realm of names,

How Carl Linnaeus brought order and linguistic games.

Latin adjectives for animals, adding flavor to our speech,

A legacy of classification that Carl Linnaeus did beseech.
