Amicus barbam radit.

Because amicus is in the nominative singular, which is the case Latin normally uses for the subject of a sentence.

Here, the verb radit is also 3rd person singular (he/she/it shaves), so it matches a singular subject. That makes amicus the one doing the action.

By contrast, barbam is in the accusative, which marks the direct object.

Because barbam is the accusative singular form of barba.

• barba = nominative singular, the form you would use for the subject
• barbam = accusative singular, the form used for the direct object

Since the beard is what is being shaved, Latin puts barba into the accusative: barbam.

Radit is the 3rd person singular present active indicative of radere.

That means:

• present = happening now / generally
• active = the subject does the action
• indicative = a normal statement
• 3rd person singular = he/she/it shaves

So radit means shaves or sometimes is shaving, depending on context.

Because Latin does not have articles like English the and a/an.

So:

• amicus can mean a friend or the friend
• barbam can mean a beard or the beard

Which one sounds best in English depends on context, not on a separate Latin word.

Latin often leaves out possessive words like his, her, or their when the ownership is obvious, especially with body parts.

So barbam radit naturally suggests he shaves his beard unless context tells you otherwise.

Latin could say barbam suam radit, but that is often unnecessary when it is already clear whose beard is meant.

Yes. The Latin present tense can cover both ideas:

• he shaves
• he is shaving

Latin does not always separate those two meanings as sharply as English does. Context tells you which one is more natural.

No. Latin word order is much freer than English word order because the endings show each word’s job in the sentence.

So all of these could mean the same basic thing:

• Amicus barbam radit
• Barbam amicus radit
• Radit amicus barbam

The choice of order usually affects emphasis or style, not the basic grammar.

Because the ending of the verb already tells you the person and number.

In radit, the ending -t means 3rd person singular. So Latin already tells you he/she/it shaves without needing a separate pronoun.

Latin can add is or another pronoun, but usually only for emphasis or clarity.

A learner would usually look them up as:

• amicus, amici = friend
• barba, barbae = beard
• rado, radere, rasi, rasum = shave, scrape

That tells you:

• amicus is a 2nd-declension noun
• barba is a 1st-declension noun
• radere is a 3rd-conjugation verb

Yes, Latin nouns have grammatical gender.

• amicus is masculine
• barba is feminine

This matters because adjectives and some pronouns must agree with the noun’s gender, number, and case.

But grammatical gender does not always mean natural gender. For example, barba is feminine as a noun even though a beard is not biologically female. That is just how the noun is classified in Latin.

In theory, amicus can be an adjective meaning friendly. But in this sentence it is naturally understood as the noun friend.

Why? Because it stands on its own as the subject, and there is no noun for it to describe. So here it is read as a friend / the friend, not friendly.

The pattern is:

subject + direct object + verb

So:

• amicus = subject
• barbam = direct object
• radit = verb

That is a very common Latin pattern, although Latin can rearrange the order more freely than English.
