הוא אדיב מאוד לאורחים, ובשביל שכולם ירגישו בנוח הוא פותח את הדלת ומציע תה.

Both הוא אדיב מאוד and הוא מאוד אדיב are possible in Hebrew.

In this sentence, אדיב מאוד means very polite / very kind, with מאוד coming after the adjective. That is extremely common in Hebrew.

So:

• הוא אדיב מאוד = he is very polite
• הוא מאוד אדיב = also he is very polite

The version in the sentence just sounds natural and idiomatic.

Also, לאורחים adds to/toward the guests, so the full idea is He is very polite to the guests.

לאורחים is made of:

• ל־ = to / toward
• אורחים = guests (masculine plural)

So לאורחים literally means to the guests or toward the guests.

With adjectives like אדיב (polite, courteous), Hebrew often uses ל־ to show who the politeness is directed toward:

• הוא אדיב לאורחים = He is polite to the guests
• היא אדיבה לילדים = She is kind to the children

Because אורחים has the definite sense the guests here, the ל־ combines with ה־:

• ל + האורחים → לאורחים

ובשביל ש־ means and so that... or and in order that...

It breaks down like this:

• ו־ = and
• בשביל = for / for the sake of / in order to
• ש־ = that

So:

• ובשביל שכולם ירגישו בנוח... = and so that everyone will feel comfortable...

In everyday Hebrew, בשביל ש־ is common in speech. It is often similar in meaning to כדי ש־.

For example:

• הוא מדבר בשקט בשביל שהתינוק יישן = He speaks quietly so that the baby will sleep
• הוא פותח את הדלת בשביל שכולם ירגישו בנוח = He opens the door so that everyone will feel comfortable

Yes. In this sentence, בשביל שכולם ירגישו בנוח and כדי שכולם ירגישו בנוח are very close in meaning.

So you could say:

• ובשביל שכולם ירגישו בנוח...
• וכדי שכולם ירגישו בנוח...

Both mean so that everyone will feel comfortable.

A useful nuance:

• כדי ש־ can sound a bit more neutral or formal
• בשביל ש־ often sounds more conversational

But in ordinary modern Hebrew, both are very common.

Because כולם means everyone / all of them, and grammatically it takes a plural verb.

So:

• כולם ירגישו = everyone will feel
• not כולם ירגיש

Hebrew often treats everyone as grammatically plural, even though English uses singular agreement in meaning.

More examples:

• כולם יודעים = everyone knows
• כולם רוצים = everyone wants
• כולם יבואו = everyone will come

So ירגישו is the correct plural future form here.

Because after בשביל ש־ (so that), Hebrew commonly uses the future tense to express the intended result.

So:

• בשביל שכולם ירגישו בנוח literally = so that everyone will feel comfortable
• in smoother English = so that everyone feels comfortable

This is very normal Hebrew structure.

Compare:

• הוא מסביר לאט כדי שיבינו = He explains slowly so that they understand / will understand
• היא סוגרת את החלון בשביל שלא יהיה קר = She closes the window so that it won’t be cold

So even if the main sentence is present tense, the purpose clause often uses future.

בנוח means comfortable / at ease.

It is a very common expression in Hebrew:

• להרגיש בנוח = to feel comfortable
• תרגיש בנוח = make yourself comfortable / feel free
• אני לא מרגיש בנוח פה = I don’t feel comfortable here

Literally, בנוח is like in comfort / at ease, but you should learn להרגיש בנוח as a set phrase.

So:

• שכולם ירגישו בנוח = so that everyone will feel comfortable / at ease

פותח and מציע are present-tense forms:

• פותח = opens
• מציע = offers

Hebrew present tense is often used for:

• actions happening now
• habitual actions
• general behavior

Here, the sentence describes what he does as part of his polite behavior. So the present tense works like English he opens the door and offers tea.

This gives a sense of a typical or repeated action:

• he is the kind of person who opens the door and offers tea

Because תה here means tea in an indefinite, general sense.

• מציע תה = offers tea
• מציע את התה = offers the tea

In the sentence, he is not offering one specific tea already known to the listener; he is just offering tea in general, which is why there is no ה־ and no את.

Compare:

• הוא מציע קפה = He offers coffee
• הוא מציע את הקפה שהכין = He offers the coffee that he made

Actually, in this sentence there is no את at all, and the reasons are different for each noun.

1. הדלת

The phrase is פותח את הדלת — and here את is present.

Breakdown:

• פותח = opens
• את = marker of a definite direct object
• הדלת = the door

So את is used because הדלת is definite.

2. תה

The phrase is מציע תה — here there is no את.

That is because תה is indefinite:

• tea not
• the tea

Rule:

• use את before a definite direct object
• do not use את before an indefinite direct object

So:

• פותח את הדלת = opens the door
• מציע תה = offers tea

Yes, it often could be omitted.

Hebrew frequently drops subject pronouns when the verb already makes the subject clear. So a version like this would also be natural:

• הוא אדיב מאוד לאורחים, ובשביל שכולם ירגישו בנוח פותח את הדלת ומציע תה.

However, keeping הוא can make the sentence clearer, more balanced, or slightly more emphatic:

• he is the one opening the door and offering tea

So both are possible, but the version with הוא is perfectly natural.

In Hebrew, the masculine plural is often the default form for mixed groups or for people in general.

So:

• כולם = everyone / כולם
• ירגישו = masculine plural future

This does not necessarily mean the group is all male. It can refer to:

• a mixed group
• an unspecified group
• people in general

If the sentence were clearly about an all-female group, you might see feminine plural forms, but in general Hebrew often uses masculine plural as the default.

You would change the masculine singular forms to feminine singular:

• היא אדיבה מאוד לאורחים, ובשביל שכולם ירגישו בנוח היא פותחת את הדלת ומציעה תה.

Changes:

• הוא → היא
• אדיב → אדיבה
• פותח → פותחת
• מציע → מציעה

But כולם ירגישו stays the same, because כולם is still plural and is being used in the general/default masculine plural sense.
