En nia teamo afabla respondo ofte helpas pli ol laŭta respondo.

Because en is a preposition, and after a preposition Esperanto normally does not use the accusative -n for simple location.

So:

• en nia teamo = in our team
• nian teamon would not fit here

A useful contrast is:

• en la domo = in the house
• en la domon = into the house (direction/movement)

Here there is no movement, just location or context.

Because they are adjectives. In Esperanto, adjectives always end in -a.

• afabla = kind
• laŭta = loud
• respondo = response

Adjectives also agree with the noun they describe. Since respondo is singular and has no -n, the adjectives stay in the basic form too:

• afabla respondo
• laŭta respondo

Esperanto has no indefinite article. So a bare noun like respondo can mean a response or sometimes just response in a general sense.

Esperanto only has the definite article la, meaning the.

So:

• respondo = a response / response
• la respondo = the response

In this sentence, the speaker is making a general statement, so no la is needed.

Because helpas is the present-tense verb form: helps.

In Esperanto:

• helpi = to help (infinitive)
• helpas = helps / is helping (present)
• helpis = helped
• helpos = will help

Here the subject is afabla respondo, so the sentence needs a finite verb: afabla respondo ... helpas.

Not necessarily. Just like in English, help can be used in a general way.

Here afabla respondo ofte helpas means something like:

• a kind response is often helpful
• a kind response often helps

The sentence does not say exactly whom or what it helps, because that is left general. If you wanted to be specific, you could add an object, for example helpas la teamon.

Ofte means often. It is an adverb, and Esperanto adverbs usually end in -e.

It modifies the verb helpas, so the idea is often helps.

Its position is fairly flexible. This sentence uses a very natural order:

• afabla respondo ofte helpas

You could also see:

• ofte afabla respondo helpas
• afabla respondo helpas ofte

But the version in the sentence is the most straightforward.

Pli means more, and ol means than.

Together, pli ol makes a comparison:

• pli ol laŭta respondo = more than a loud response

So the whole comparison is:

• afabla respondo ofte helpas pli ol laŭta respondo
• a kind response often helps more than a loud response

This is the normal Esperanto way to make comparisons.

It is repeated for clarity and balance:

• afabla respondo ... pli ol laŭta respondo

That makes the comparison very clear: one kind of response is being compared with another kind of response.

In some contexts, Esperanto can omit a repeated noun if it is obvious, but keeping respondo here is very natural and especially clear for learners.

It can mean either, depending on context.

• answer if it is a reply to a question
• response if it is a reaction more generally

In this sentence, response is probably the broadest and most natural translation, because the idea is about the way someone reacts or replies.

Yes. Esperanto word order is more flexible than English because endings show grammatical roles clearly.

For example, you could also say:

• Afabla respondo ofte helpas pli ol laŭta respondo en nia teamo.
• Ofte afabla respondo helpas pli ol laŭta respondo en nia teamo.

But the original sentence is smooth and natural because it starts with the setting, En nia teamo, and then gives the main statement.

The important part is aŭ, which is a diphthong, roughly like ow in cow.

So laŭta is approximately:

• LOW-tah

Also remember that Esperanto normally stresses the second-to-last syllable, so the stress is on laŭ.
