Das Geschlecht ist hier nicht wichtig.

Geschlecht can mean sex or gender, depending on context.

In German, it can refer to:

• biological sex
• social gender
• even grammatical gender in some contexts

So in a sentence like Das Geschlecht ist hier nicht wichtig, the exact English translation depends on the situation. If the topic is people, it may mean sex or gender. If the topic is grammar, it could mean grammatical gender.

Because Geschlecht is a neuter noun in German, so its article is das.

German nouns have grammatical gender:

• der = masculine
• die = feminine
• das = neuter

So the dictionary form is das Geschlecht.

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

In Das Geschlecht ist hier nicht wichtig:

• Das Geschlecht = the subject
• ist = the verb
• hier nicht wichtig = the rest of the predicate

Since the subject is nominative, the article stays das.

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

That means the finite verb comes in position 2:

• Das Geschlecht = position 1
• ist = position 2
• hier nicht wichtig = the rest

This is a very important German word-order rule.

Because wichtig is a predicate adjective here, not an adjective directly in front of a noun.

Compare:

• ein wichtiges Thema = an important topic
  
  • here the adjective is before a noun, so it takes an ending
• Das Thema ist wichtig = the topic is important
  
  • here it comes after sein, so it does not take an ending

In your sentence:

• Das Geschlecht ist wichtig
• so wichtig stays in its basic form

Because nicht is negating the idea of being important.

So:

• wichtig = important
• nicht wichtig = not important

This is very common in German: nicht often comes before the adjective or phrase it negates.

So the sentence means that the gender/sex is not important.

Yes, hier literally means here, but in many sentences it can also mean something like:

• in this case
• here
• in this context

So depending on context, hier may refer:

• to a physical place: here
• to the current discussion or situation: in this case / here

In this sentence, hier often feels like in this situation or for this matter.

Yes, that is possible, but Das Geschlecht ist hier nicht wichtig usually sounds more natural.

The version with hier before nicht wichtig more smoothly groups the sentence like this:

• here/in this context
  • not important

If you put hier at the end, it may sound a little more marked or emphatic, as if you are especially contrasting here with somewhere else.

Yes. unwichtig means unimportant, so it is very close in meaning to nicht wichtig.

Compare:

• nicht wichtig = not important
• unwichtig = unimportant

In many situations they are interchangeable.
However, nicht wichtig can sound a little more neutral and conversational, while unwichtig can sometimes sound slightly more direct or compact.

Yes, very often German uses the singular when talking about a concept in general.

So Das Geschlecht here refers to the concept of gender/sex as a category, not necessarily to one specific gender.

English often does something similar:

• Gender is not important here
• The gender is not important here

German commonly uses the singular for this kind of abstract statement.

By itself, the sentence does not tell you for sure. You need the surrounding context.

Because Geschlecht can mean different things, the sentence could refer to:

• a person’s sex
• a person’s gender
• the grammatical gender of a noun

So a learner should not assume only one meaning from the word alone. Context decides.

Yes. German allows that because of the verb-second rule.

For example:

• Hier ist das Geschlecht nicht wichtig.

That is also correct. The meaning is very similar, but now hier is more strongly emphasized because it comes first.

This shows an important German pattern:

• whatever comes first is often the topic or emphasis
• the finite verb still stays in second position

A natural pronunciation would be something like:

das guh-SHLEKHT ist heer nikht VIKH-tikh

A few useful points:

• Geschlecht has the ch sound like in Bach, not like English ch in chair
• ich in wichtig is the softer German ch sound
• nicht also has that ch sound, not a hard k

The main stress is usually on:

• Geschlecht
• wichtig

So the rhythm is roughly: Das GeSCHLECHT ist hier nicht WICHtig.
