Diese Parklücke ist zu klein, also fahren wir weiter.

Because Parklücke is a feminine noun in German: die Parklücke.

In the sentence, diese Parklücke is the subject, so it is in the nominative case. The nominative feminine form of dies- is diese.

So:

• dieser = masculine nominative, or feminine dative/genitive in some contexts
• diese = feminine nominative/accusative, or plural nominative/accusative
• dieses = neuter nominative/accusative

Here we need feminine nominative singular, so diese is correct.

Parklücke literally means a gap for parking or parking space.

It is a compound noun:

• Park- = parking
• Lücke = gap, opening, space

So Parklücke often refers to an available space between cars where you might park, especially on a street.

It is slightly more specific than Parkplatz, which can mean a parking spot in general or even a parking lot depending on context.

Ist is the 3rd person singular form of sein (to be).

The subject is diese Parklücke, which is a singular thing, so German uses:

• ich bin
• du bist
• er/sie/es ist

So:

• Diese Parklücke ist ... = This parking space is ...

Zu klein means too small, not just small.

This is a very common German pattern:

• zu + adjective = too + adjective

Examples:

• zu groß = too big
• zu teuer = too expensive
• zu eng = too narrow
• zu klein = too small

So:

• Die Parklücke ist klein = The parking space is small.
• Die Parklücke ist zu klein = The parking space is too small.

The second one implies it is not suitable for what you want.

Because klein comes after the verb ist and is being used as a predicate adjective.

In German, adjectives behave differently depending on where they are:

1. Before a noun: they take endings

   • eine kleine Parklücke

2. After verbs like sein, werden, bleiben: they do not take endings

   • Die Parklücke ist klein
   • Die Parklücke ist zu klein

So here klein stays in its basic form.

Here also means so, therefore, or for that reason.

In this sentence:

• Diese Parklücke ist zu klein, also fahren wir weiter.
• This parking space is too small, so we drive on / so we keep going.

A very important point for English speakers: German also usually does not mean English also.

Usually:

• German also = so / therefore
• English also = German auch

For example:

• Ich komme auch. = I’m coming too / also.
• Es regnet, also bleiben wir zu Hause. = It’s raining, so we’re staying home.

Because German main clauses normally follow the verb-second rule.

When also comes first, it takes the first position in the clause, and the conjugated verb must come next:

• Also fahren wir weiter.

Structure:

• Position 1: also
• Position 2: fahren
• then: wir
• then: weiter

This is a very common German word-order pattern.

Compare:

• Wir fahren weiter.
• Deshalb fahren wir weiter.
• Dann fahren wir weiter.

In all of these, the verb still stays in second position.

Here weiter means further, on, or continue.

With fahren, it often means:

• keep driving
• drive on
• go on

So:

• wir fahren weiter = we continue driving / we drive on

Some other examples:

• Gehen Sie bitte weiter. = Please go on / move along.
• Wir machen weiter. = We continue.
• Lies weiter! = Keep reading!

Because fahren is used for traveling by vehicle.

Since the context is a parking space, the speakers are presumably in a car, so fahren is the natural verb.

Very roughly:

• gehen = go on foot, walk
• fahren = go/travel/drive in or on a vehicle

So:

• Wir gehen weiter = We continue walking.
• Wir fahren weiter = We continue driving / go on by car.

The full verb is often thought of as weiterfahren.

In a conjugated main clause, German separates many prefix verbs:

• Wir fahren weiter.

But in the infinitive or at the end of a clause, it appears together:

• Wir wollen weiterfahren.
• Es ist besser, weiterzufahren.

So both ideas are connected:

• dictionary form: weiterfahren
• finite main clause: fährt weiter, fahren weiter

It is in the nominative case because it is the subject of the sentence.

The sentence is saying something about the parking space:

• Diese Parklücke = the thing being described
• ist zu klein = is too small

That makes it the subject, so nominative is used.

German often uses the present tense where English might prefer a future form.

So wir fahren weiter can naturally mean:

• we drive on
• we’re continuing
• we’ll keep driving

The exact English translation depends on context, but the German present tense is completely normal here.

German often relies on context instead of using a separate future tense:

• Morgen fahre ich nach Berlin. = Tomorrow I’m going to Berlin / I’ll go to Berlin.
• Also fahren wir weiter. = So we’ll continue driving / So we go on.

Because in German, all nouns are capitalized.

So in this sentence:

• Parklücke is capitalized because it is a noun.

Other words are not capitalized unless they begin the sentence or are proper nouns.

This is one of the most noticeable differences from English spelling.

Yes. Depending on tone and style, you could use other connectors such as:

• deshalb
• daher
• darum

For example:

• Diese Parklücke ist zu klein, deshalb fahren wir weiter.
• Diese Parklücke ist zu klein, daher fahren wir weiter.

These all mean something like therefore / so / for that reason.

They also trigger the same word order pattern in the second clause:

• deshalb fahren wir weiter
• not deshalb wir fahren weiter

So they are good alternatives, but also sounds very natural in everyday speech.
