כנראה נישאר בבית הערב, כי שנינו עייפים מאוד.

In this sentence, כנראה means probably.

Depending on context, כנראה can mean either:

• probably
• apparently
• it seems

Here, with a future verb (נישאר), the most natural English meaning is probably:

• כנראה נישאר... = We’ll probably stay...

It often appears near the beginning of the sentence, but Hebrew word order is fairly flexible.

Because the verb itself already shows the subject.

נישאר is the 1st person plural future form of the verb להישאר (to stay / to remain), so it already means:

• we will stay
• we will remain

The prefix נ- often marks we in the future tense.

So Hebrew does not need אנחנו here, although you could add it for emphasis:

• כנראה אנחנו נישאר בבית הערב = We’ll probably stay home tonight

Usually, though, the pronoun is omitted because the verb already makes it clear.

It comes from להישאר = to stay / to remain.

Some useful forms:

• להישאר = to stay
• נשאר = he stayed / remained
• נשארים = staying / remain
• נישאר = we will stay

So in this sentence:

• כנראה נישאר בבית = We’ll probably stay at home

This verb is very common in everyday Hebrew.

It is pronounced roughly nee-sha-AR.

A helpful point for English speakers: the א in the middle helps separate the vowels, so it is not one smooth syllable like nishar. It is more like:

• ni-sha-ar

In normal speech, it may sound a bit smoother, but the main stress is on the last syllable.

In Hebrew, prepositions like ב (in / at) are often attached directly to the following word.

So:

• ב = in / at
• בית = house / home
• בבית = in the house / at home

In this sentence, בבית means at home.

This is very normal in Hebrew. Other common attached prepositions are:

• ל = to
• כ = like / as
• מ = from

Literally, it can mean in the house, but in many everyday contexts it means at home.

Here, the natural meaning is:

• נישאר בבית הערב = We’ll stay home tonight

So even though the literal idea is in the house, the idiomatic English translation is usually at home or home.

Hebrew often uses time expressions with ה in ways that sound more natural in English as this evening or tonight.

So:

• ערב = evening
• הערב = this evening / tonight

In context:

• בבית הערב = at home tonight

This is one of those places where a very literal translation (the evening) sounds unnatural in English, even though the Hebrew is perfectly normal.

Here, כי means because.

So the second part of the sentence explains the reason:

• כי שנינו עייפים מאוד = because both of us are very tired

Be aware that כי can also mean that in other sentences, so its exact meaning depends on context.

Examples:

• אני חושב כי... = more formal/literary I think that...
• נישאר בבית, כי אנחנו עייפים = We’ll stay home because we’re tired

שנינו means both of us or we both.

It refers specifically to two people.

So:

• שניים = two
• שנינו = the two of us / both of us

In the sentence:

• כי שנינו עייפים מאוד = because both of us are very tired

This tells you the speaker is talking about two people, not a larger group.

Yes, but the meaning would be a little less specific.

• כי אנחנו עייפים מאוד = because we are very tired
• כי שנינו עייפים מאוד = because both of us are very tired

שנינו emphasizes that there are exactly two people, and both are tired.

You can also combine them:

• כי אנחנו שנינו עייפים מאוד

But very often שנינו by itself is enough.

Because it agrees with the subject שנינו (both of us), which is plural.

Hebrew adjectives must agree in gender and number.

Here:

• עייף = tired (masculine singular)
• עייפה = tired (feminine singular)
• עייפים = tired (masculine plural)
• עייפות = tired (feminine plural)

So עייפים is used if:

• the two people are male, or
• the group is mixed, or
• the gender is not being specified and masculine is used as the default

If both speakers were female, you would normally say:

• כי שתינו עייפות מאוד

That is just the normal Hebrew pattern.

Hebrew usually places מאוד (very) after the adjective:

• עייף מאוד = very tired
• יפה מאוד = very beautiful / very nice
• גדול מאוד = very big

So:

• עייפים מאוד = very tired

This is a very common difference from English word order.

Yes—sort of.

In present-tense Hebrew, there is usually no separate word for is / am / are.

So:

• שנינו עייפים מאוד literally looks like both of us very tired
• but it means both of us are very tired

This is completely normal Hebrew.

Compare:

• אני עייף = I am tired
• היא בבית = She is at home
• הם שמחים = They are happy

There is no present-tense to be in ordinary sentences like these.

Yes, to some extent. Hebrew word order is flexible, especially with adverbs like כנראה.

For example, these are all possible with slightly different emphasis:

• כנראה נישאר בבית הערב
• נישאר כנראה בבית הערב
• הערב כנראה נישאר בבית

The version in your sentence is very natural and neutral. Starting with כנראה gives the sentence a smooth Probably, ... feeling right away.

It is very natural everyday Hebrew.

Nothing in it sounds unusually formal or literary. In spoken Hebrew, a person could easily say:

• כנראה נישאר בבית הערב, כי שנינו עייפים מאוד.

A more casual speaker might also use slightly different wording, such as:

• נראה לי שנישאר בבית הערב...
• כנראה נשאר בבית הערב... in very casual speech

But your sentence is standard, natural, and correct.
