Looking at the word verso, we can detect a couple of cognates: "verse" and "versus," abbreviated as "vs" or "v." We can also see the word in words like "reverse..."
Verso is actually a wonderful word that can be used in so many circumstances. But where to start? Let's start in earlier times.
If you look at a medieval manuscript, for example, and think of how they numbered the pages, it's pretty interesting.
Instead of pages, they considered the whole sheet or leaf. Think of a looseleaf notebook. A leaf, or a sheet of paper (or parchment), has two sides. When scribes started numbering these leaves (in the twelfth century "foliation" became a rule. Before that there were different ways of keeping track), the number would be placed in the upper right-hand corner, for example: "XXX" (roman numerals were commonly used). This was the right side, the front side, the "recto." The backside of the leaf was called the "verso," the reverse side. So if you were indicating where a song or chapter started, you would say folio XXX r or XXX v.
The word verso comes from the Latin verb "vertĕre," meaning "to turn" — in its past participle form, "versus." The Italian verb meaning "to turn" is voltare which has common origins with volgere, the Italian for Latin "vertere." So the backside of a sheet is the one you have "turned."
Considering the above, it seems appropriate to discuss the noun form il verso next.
Il verso can certainly mean, as we have seen, "the reverse side," especially when talking about a coin, medal, or sheet or leaf of parchment.
It can also mean "direction" or "way."
...e per trenta minuti si gira in un verso, lentamente,
...and for thirty minutes, you stir it in one direction, slowly,

We also have the word inverso in Italian, meaning "inverse" or "opposite."
Quando "venire" è contrapposto esplicitamente ad "andare", indica movimento inverso, perché i due verbi esprimono insieme un movimento alternato e ripetuto nei [due] sensi.
When “venire” is explicitly juxtaposed with “andare,” it indicates an inverse movement, because the two verbs together express alternate and repeated movements, direction-wise.

Other meanings of il verso as a noun are:
-the sound an animal makes.
-a line of poetry
Verso is a preposition, too, again having to do with direction.
Verso can mean "towards." It can also be interpreted as "facing,"
Perciò ti volti verso di lui. -Certo.
So, you turn towards him. -Of course.Play Caption
Note that when we use personal pronouns as an object, we need the extra preposition di. If it's a noun, then no extra preposition is needed.
Poi andando sempre più verso il Duomo, si vede appunto il Duomo
Then still going towards the Duomo, you can see just that, the Cathedral,

When we're talking about directions rather than concrete destinations, we use neither an extra preposition nor an article.
Poi, andando verso sinistra si vede il Palazzo Vecchio,
Then, going towards the left you can see the Palazzo Vecchio [the old building]

The English word "versus," has the same Latin origin as the preposition verso, but has come to mean "against." Two people or teams face each other when they are against each other.
Verso can mean "around" especially when talking about time.
La signora ha cenato e poi verso le nove è uscita.
The lady had dinner and then around nine, she went out.Play Caption
Finally, we mention the verb versare, because the first person singular happens to be verso. But versare deserves a lesson all to itself, because it's used often, but with various nuances in specific contexts.
