Haec via utilior est quam illa, quia ad forum ducit.

Haec means this and agrees with via.

• via is feminine singular nominative
• so the demonstrative must also be feminine singular nominative
• that gives haec via = this road

Latin demonstratives change form to match the noun’s gender, number, and case.

Because via is the subject of est.

In Haec via utilior est, the basic structure is:

• haec via = the subject, this road
• utilior = predicate adjective, more useful
• est = is

So via must be nominative, just as English uses the subject form in This road is...

Utilior is the comparative form of utilis (useful).

So:

• utilis = useful
• utilior = more useful

It agrees with via in number and case, and in the comparative the same nominative singular form utilior is used for both masculine and feminine.

So here:

• via is feminine singular nominative
• utilior is nominative singular and matches it

Latin often can leave out forms of to be, but here est is expressed.

So:

• Haec via utilior est = This road is more useful

You might also see Latin omit est in some contexts, especially in poetry or very compact prose, but in a normal beginner sentence it is very natural to include it.

Quam is used to introduce the second part of a comparison: than.

So:

• utilior quam illa = more useful than that one

This is the standard way to make a comparison in Latin:

• comparative adjective + quam
• for example, maior quam... = bigger than...
• celerior quam... = faster than...

Because illa is standing for illa via and is in the same case as the thing being compared.

Here the comparison is really:

• Haec via utilior est quam illa via

Both roads are being compared as subjects, so both are nominative:

• haec via = nominative
• illa (via) = nominative

Latin often leaves out a repeated noun when it is obvious, so via after illa is omitted.

Illa means that or that one, and here it means that road.

The noun via is understood but not repeated:

• haec via = this road
• illa = that one, meaning that road

This is very common in Latin. If the noun is obvious from context, Latin often omits it.

Quia means because and introduces a reason.

So:

• quia ad forum ducit = because it leads to the forum

This clause explains why the road is more useful.

The subject of ducit is still haec via.

Latin often does not repeat the subject if it is already clear. So the sentence means:

• This road is more useful than that one, because [this road] leads to the forum.

The verb ending -t tells you it is third person singular: he/she/it leads.

Since via is the thing being talked about, the meaning is it leads.

Ducit is:

• present tense
• active voice
• indicative mood
• third person singular

It comes from ducere, which often means to lead.

So ad forum ducit literally means leads to the forum.

With roads, paths, and doors, Latin commonly uses ducere in the sense to lead to.

Because ad means to or toward, and it takes the accusative case.

So:

• ad
  • accusative
• forum here is accusative singular

This shows motion toward a place:

• ad forum = to the forum

Because forum is a second-declension neuter noun.

For many neuter nouns in Latin:

• nominative singular = accusative singular

So:

• nominative: forum
• accusative: forum

Even though the form looks the same, after ad it must be understood as accusative.

Latin often leaves out subject pronouns when the verb ending already shows the person and number.

So instead of saying a separate word for it, Latin simply says:

• ducit = it leads

The ending -t already tells you the subject is third person singular. Context tells you that the it is the road.

Its basic meaning is more useful, because it comes from utilis.

In context, though, English might sometimes naturally say:

• better
• more useful
• more practical

But grammatically the Latin word specifically means more useful / more advantageous.

In both Latin and English, this is a normal figurative way to speak.

• English: This road leads to the city
• Latin: Haec via ad forum ducit

So ducit does not mean the road is actively dragging someone somewhere. It means the road goes to, takes you to, or provides the way to that place.

Latin word order is much more flexible than English word order because Latin uses case endings to show grammatical relationships.

This sentence is arranged quite naturally in Latin:

• Haec via = topic / subject
• utilior est quam illa = main statement
• quia ad forum ducit = reason

English relies heavily on word order, but Latin can move words around more freely without changing the basic meaning.

Yes, Latin can often vary word order, and something like Haec via quam illa utilior est would still be understandable.

However, Haec via utilior est quam illa is a very straightforward and common order for learners:

• subject
• comparative adjective + est
• quam phrase

So the given version is clear and idiomatic.

It is feminine because it refers to via, which is feminine.

If the noun being referred to were masculine or neuter, the demonstrative would change:

• ille = masculine
• illa = feminine
• illud = neuter

Since via is feminine, the correct form is illa.
