Die letzte Silbe klingt in diesem Wort anders.

Because Silbe means syllable, and Silbe is a feminine noun in German: die Silbe.

So in the nominative singular, the phrase is:

• die = the
• letzte = last
• Silbe = syllable

The adjective letzte takes the ending -e because it comes after the definite article die and agrees with the feminine singular noun Silbe.

Letzte means last.

In this sentence, die letzte Silbe means the last syllable of the word.

This is the feminine form of the adjective letzt-. The ending changes depending on the noun it describes:

• der letzte Laut = the last sound
• die letzte Silbe = the last syllable
• das letzte Wort = the last word

Klingt is the 3rd person singular form of the verb klingen, which means to sound.

The subject of the sentence is die letzte Silbe, which is singular, so German uses the singular verb form:

• ich klinge
• du klingst
• er/sie/es klingt

So:

• Die letzte Silbe klingt ... = The last syllable sounds ...

Because anders works like an adverb here and describes how the syllable sounds: differently.

German often places this kind of information toward the end of the sentence, especially after location phrases like in diesem Wort.

So the structure is:

• Die letzte Silbe = subject
• klingt = verb
• in diesem Wort = in this word
• anders = differently

This word order is very natural in German.

Because in can take either the accusative or the dative, depending on meaning.

Here, in diesem Wort describes a location or context: in this word. There is no movement into something, so German uses the dative.

• diesem Wort = dative singular
• Wort is a neuter noun: das Wort

So:

• nominative: dieses Wort
• accusative: dieses Wort
• dative: diesem Wort

That is why the sentence has in diesem Wort.

You learn it as das Wort.

German nouns have grammatical gender, and Wort is one of the neuter ones. Because of that, the demonstrative this changes accordingly:

• dieser for masculine nouns
• diese for feminine nouns
• dieses for neuter nouns in nominative/accusative
• diesem for dative singular

Since Wort is neuter and follows in in a dative context, you get diesem Wort.

Here, anders means different or differently.

In English, we would usually say:

• The last syllable sounds different in this word.

German uses anders very naturally for this idea.

A few similar examples:

• Das klingt anders. = That sounds different.
• Er sieht anders aus. = He looks different.
• Heute ist alles anders. = Today everything is different.

Yes. In many cases, klingen works very much like English to sound.

Examples:

• Das klingt gut. = That sounds good.
• Das klingt komisch. = That sounds strange.
• Die letzte Silbe klingt anders. = The last syllable sounds different.

So this sentence uses a very common and natural German pattern.

Because all nouns are capitalized in German.

So in this sentence:

• Silbe is a noun
• Wort is a noun

That is why they begin with capital letters.

This is one of the most noticeable spelling differences between German and English.

Silbe is pronounced approximately like ZIL-buh.

A few pronunciation points:

• S at the beginning of Silbe sounds like z in many standard pronunciations.
• The i is short, like in sit.
• The e at the end is a weak uh sound, not a strong English ee.

So it is roughly:

• Silbe → ZIL-buh

Yes. A very common alternative is:

• Die letzte Silbe hört sich in diesem Wort anders an.

This also means that the last syllable sounds different in this word.

However, klingt is shorter and very natural, so the original sentence is perfectly good German.

You could say it, but it is not the best choice if you specifically mean the sound.

• ist anders = is different
• klingt anders = sounds different

If you are talking about pronunciation, klingt anders is much clearer and more natural.

So for this sentence, klingt anders is the better wording.
