בילוי בפארק עם חברות נשמע לי טוב.

בילוי is a noun meaning spending time for fun, hanging out, an outing, or a leisure activity.

It comes from the verb לבלות (to have fun / to spend time / to hang out).

So here, בילוי refers to the activity itself, not a person doing it.

Hebrew does not have a separate word for a/an.

A bare noun like בילוי can mean:

• an outing
• some time out
• hanging out
• a general idea of leisure time

If the noun were definite, Hebrew would usually add ה־:

• הבילוי = the outing / the leisure activity

So בילוי here is indefinite or general.

בפארק is ב־ + פארק.

• ב־ usually means in, at, or sometimes inside
• פארק = park

So בפארק means in the park or at the park.

A useful detail: in unvocalized Hebrew, בפארק can sometimes be ambiguous between:

• in a park
• in the park

The written form is the same, and context usually tells you which meaning is intended.

Here חברות means female friends.

The singular is חברה, which can mean:

• female friend
• girlfriend in some contexts
• company in other contexts

The plural חברות can therefore mean:

• female friends
• girlfriends
• companies

In this sentence, because of the context with חברות, it clearly means with female friends.

If the group were male or mixed, Hebrew would more often use חברים.

Because there is no possessive ending or word like שלי.

עם חברות means something like:

• with female friends
• with some female friends

If you wanted to say with my female friends, you would say:

• עם החברות שלי = with my female friends
• עם חברות שלי = with some female friends of mine

So the original sentence is less specific.

Because the grammatical subject is בילוי, and בילוי is masculine singular.

The full subject is:

בילוי בפארק עם חברות

But the head noun of that whole phrase is still בילוי.

So the verb agrees with בילוי, not with חברות.

That is why you get:

• נשמע = masculine singular

not:

• נשמעות = feminine plural

Even though חברות is plural, it is only part of the phrase עם חברות (with friends), not the main subject.

נשמע comes from the root ש־מ־ע, related to hearing.

The basic verb שמע means heard or listened depending on context.

נשמע is from the נפעל pattern, and here it means sounds.

So in this kind of sentence, Hebrew uses נשמע the same way English uses sounds:

• זה נשמע טוב = That sounds good
• הרעיון נשמע מעניין = The idea sounds interesting

So it is a very common and natural way to express an opinion.

לי literally means to me.

In Hebrew, with verbs like נשמע, the person who experiences the impression is often marked with ל־:

• נשמע לי טוב = sounds good to me
• literally: sounds to me good

So לי is not optional if you want to include the idea to me.

Compare:

• נשמע טוב = sounds good
• נשמע לי טוב = sounds good to me

טוב is masculine singular, and it matches בילוי, which is also masculine singular.

So the agreement is:

• בילוי → masculine singular
• נשמע → masculine singular
• טוב → masculine singular

If the subject were feminine singular, you would expect:

• נשמעת לי טובה

For example:

• הצעה נשמעת לי טובה = The suggestion sounds good to me

So טוב is used because of grammatical agreement with בילוי.

Yes, this word order is natural.

Hebrew is somewhat flexible with word order, especially with longer noun phrases. The sentence starts with the activity/topic:

• בילוי בפארק עם חברות = the outing/hanging out in the park with female friends

and then gives the opinion:

• נשמע לי טוב = sounds good to me

A slightly different order could also work, for example:

• בילוי עם חברות בפארק נשמע לי טוב

That changes the flow a little, but not the basic meaning.

The original sentence sounds conversational and normal.

Yes. Hebrew can often express this idea either with a verbal noun or with an infinitive.

So alongside בילוי, you may also hear sentences built on לבלות.

Using בילוי makes the whole idea feel like an outing / a hangout / the activity itself.

Using לבלות would focus more directly on the act of spending time.

In everyday Hebrew, both kinds of structures are possible, but בילוי בפארק עם חברות נשמע לי טוב is completely natural.
