ההסבר הזה נשמע מסובך, אבל אולי יש דרך יעילה יותר להסביר אותו.

Because the basic noun is הסבר (explanation), and Hebrew adds the definite article ה־ to the beginning of the noun. So:

• הסבר = explanation
• ההסבר = the explanation

When the noun itself already begins with ה, you simply get two ה letters in a row in spelling: ה + הסבר = ההסבר.

In Hebrew, demonstratives like הזה / הזאת / האלה usually come after the noun, not before it as in English.

So:

• ההסבר הזה = this explanation
• literally: the-explanation this

Also, the noun normally takes the definite article when it is followed by הזה. So הסבר הזה would sound incomplete or incorrect in standard usage.

נשמע comes from the root ש־מ־ע and literally relates to hearing, but in everyday Hebrew it often means sounds in the sense of seems when described or when I hear about it.

So:

• זה נשמע טוב = that sounds good
• זה נשמע מוזר = that sounds strange
• ההסבר הזה נשמע מסובך = this explanation sounds complicated

So yes, its deeper literal idea is connected to hearing, but here it works just like English sounds.

מסובך is an adjective describing ההסבר, which is masculine singular. Adjectives in Hebrew must agree with the noun in gender and number.

• הסבר is masculine singular
• so the adjective is מסובך

You do not use ה on the adjective here because this is a predicate adjective, not an adjective directly attached before/after the noun in a noun phrase.

Compare:

• ההסבר מסובך = the explanation is complicated
• ההסבר הזה נשמע מסובך = this explanation sounds complicated

But in an attributive phrase, both noun and adjective are definite:

• ההסבר המסובך = the complicated explanation

Because אבל means but, and it connects two clauses:

• ההסבר הזה נשמע מסובך
• אבל אולי יש דרך...

In normal Hebrew writing, a comma before אבל is very common when it introduces a contrast, just like in English.

אולי means maybe / perhaps. It softens the statement and makes it sound less absolute.

So:

• יש דרך יעילה יותר = there is a more efficient way
• אולי יש דרך יעילה יותר = maybe there is a more efficient way

This makes the sentence sound more polite, tentative, or open-minded.

יש is the Hebrew existential word for there is / there are.

So:

• יש דרך = there is a way
• יש ספר = there is a book
• יש אנשים = there are people

Hebrew does not use a separate word corresponding exactly to English there in this structure. יש alone does the job.

Because דרך is a feminine singular noun, so the adjective must match it.

• דרך = way, method
• feminine singular adjective: יעילה
• masculine singular would be יעיל

So:

• דרך יעילה = an efficient way
• דרך יעילה יותר = a more efficient way

Hebrew often forms the comparative with יותר = more:

• טוב יותר = better / more good
• יעילה יותר = more efficient

That is the normal Hebrew comparative pattern:

• adjective + יותר

So Hebrew says:

• יעילה יותר = more efficient
• מהיר יותר = faster
• קשה יותר = more difficult

This is different from English, where more comes before the adjective.

This is a very common Hebrew structure: noun + infinitive, where English might use a way to...

So:

• דרך להסביר אותו = a way to explain it
• literally: a way to explain it

Other examples:

• זמן ללמוד = time to study
• מקום לשבת = a place to sit
• סיבה לחשוב כך = a reason to think so

This is very natural Hebrew.

Because Hebrew often prefers a compact noun + infinitive structure instead of a longer relative clause.

So Hebrew says:

• דרך להסביר אותו = a way to explain it

A longer version could be something like:

• דרך שאפשר להסביר בה אותו
• דרך שבה אפשר להסביר אותו

But those are heavier and less natural here. The short infinitive structure is the most idiomatic choice.

אותו refers back to ההסבר. Since הסבר is a masculine singular noun, the matching direct-object pronoun is אותו = it / him depending on context.

Here it clearly means it:

• להסביר אותו = to explain it

Hebrew uses the same form for him and it when the noun is masculine singular, so context tells you which meaning is intended.

Because להסביר takes a direct object in Hebrew.

So:

• להסביר משהו = to explain something
• להסביר אותו = to explain it

לו means to him / to it, which would mark an indirect object. That is not what is happening here.

Compare:

• להסביר את הרעיון = to explain the idea
• להסביר אותו = to explain it
• להסביר לו את הרעיון = to explain the idea to him

So אותו is the thing being explained, while לו would be the person receiving the explanation.

Yes. דרך very often means way, method, manner, not only road/path.

In this sentence:

• יש דרך יעילה יותר = there is a more efficient way / method

This is completely normal Hebrew. Very often דרך works just like English way in abstract expressions.

It breaks down like this:

• ההסבר הזה = this explanation
• נשמע מסובך = sounds complicated
• אבל = but
• אולי = maybe
• יש דרך = there is a way
• יעילה יותר = more efficient
• להסביר אותו = to explain it

So the structure is:

[subject] + [sounds + adjective], but maybe [there is] [a more efficient way] [to explain it].

This is a very natural Hebrew sentence with common everyday grammar patterns.
