Ego amo studere verbis Latinis, sed mens me non laetam facit.

Yes. Latin normally does not need the subject pronoun, because amo already means I love.

So ego is usually added for emphasis or contrast. It can suggest something like:

• I love studying Latin words...
• As for me, I love studying Latin words...

A learner should know that ego is grammatical here, but often slightly more emphatic than plain amo.

Because Latin, like English, can use an infinitive after verbs such as amo to express loving to do something.

So:

• amo studere = I love to study

This is very similar to English I love to read, I love to learn, and so on.

This is a very common question, because studere does not take a direct object in the accusative the way many English verbs do.

The verb studeo, studere normally takes the dative case, with the sense of:

• be eager for
• apply oneself to
• devote oneself to

So:

• verbis Latinis = to Latin words / to Latin vocabulary

That is why you see the dative plural:

• verbis = dative/ablative plural of verbum
• Latinis = dative/ablative plural agreeing with verbis

So the grammar is: studere verbis Latinis.

Mens is nominative singular. It is the subject of facit.

So in the second clause:

• mens ... facit = the mind ... makes

This means that mens is the thing performing the action of facit.

Also, mens is a third-declension feminine noun. Its basic form is:

• nominative: mens
• genitive: mentis

Me is the accusative form of ego. Here it is the direct object of facit.

In other words:

• mens = the subject
• facit = makes
• me = the person being affected

This is the same basic pattern as in Latin expressions like:

• hoc me beatum facit = this makes me happy

So me is correct because it is the object of makes.

This is a standard Latin pattern:

• aliquem + adjective + facere

which means:

• to make someone + adjective

So:

• me laetam facit = it makes me happy

Here laetam is not just randomly added; it is a predicate adjective describing me as the result of the action.

English does this too:

• It makes me happy
• It makes me sad

Latin expresses the same idea very naturally with facere.

Yes — this depends on the gender of the speaker.

Because laetam/laetum describes me, it must match the person speaking in natural gender:

• me laetam facit if the speaker is female
• me laetum facit if the speaker is male

So laetam is not universally right or wrong; it depends on who ego refers to.

A native English speaker often finds this surprising because English says me happy without changing the adjective for gender, but Latin does.

A learner may wonder about that, and it is a fair question.

Latin often omits possessive pronouns when the owner is clear from context. So sometimes mens can be understood as my mind without mea being stated.

However, if the writer wants to be more explicit, mea mens would make that clearer.

Also note:

• mens is feminine
• so the possessive would be mea, not mea mens
• not meus mens

So if the intended meaning is specifically my mind, mea mens is certainly possible and may sound clearer to a learner.

Latin word order is much more flexible than English word order. Non usually goes before the word or phrase it is negating, but the exact placement can vary.

Here:

• mens me non laetam facit

means that the mind does not make the speaker happy, or makes the speaker not happy.

A learner should not expect a single rigid English-style position for non. Latin often moves words around for emphasis, rhythm, or style, while the endings still show the grammar.

Sed means but. It joins the two clauses and shows a contrast:

• I love studying Latin words
• but the mind does not make me happy

So sed signals that the second idea contrasts with the first.

This is a very common conjunction, and learners will see it often.

Yes, it is possible Latin word order, though Latin has a lot of flexibility.

A few points:

• Ego amo studere verbis Latinis is understandable and straightforward.
• mens me non laetam facit also follows a common Latin pattern: subject + object + adjective + verb.
• The verb facit comes at the end, which is very common in Latin.

A native English speaker often expects one fixed order, but Latin relies much more on case endings than on word position. So the endings tell you who is doing what, even when the order shifts.
