יש לנו יום קבוע לפגישה, אבל יום רביעי לא מתאים לי.

Literally, יש לנו means there is to us.

Hebrew often expresses possession this way:

• יש = there is / there are
• לנו = to us

So:

• יש לנו יום קבוע = literally There is to us a fixed day
• natural English: We have a fixed day

This is the normal Hebrew way to say have in many situations.

Related examples:

• יש לי ספר = I have a book
• יש לך זמן? = Do you have time?
• אין לנו כסף = We don’t have money

In Hebrew, adjectives usually come after the noun they describe.

So:

• יום = day
• קבוע = fixed / regular

Together:

• יום קבוע = a fixed day

This is the normal pattern:

• בית גדול = a big house
• ילדה חכמה = a smart girl
• שולחן קטן = a small table

Also, the adjective usually matches the noun in gender and number. Here both are masculine singular:

• יום = masculine singular
• קבוע = masculine singular

קבוע means fixed, regular, set, or permanent, depending on context.

In this sentence, יום קבוע לפגישה means something like:

• a fixed day for the meeting
• a regular day for the meeting
• a set day for the meeting

So it suggests that the meeting normally happens on the same day each week or on an agreed day.

The prefix ל־ usually means to or for.

So:

• פגישה = meeting
• לפגישה = for the meeting / to the meeting

In this sentence, יום קבוע לפגישה means a fixed day for the meeting.

This use of ל־ is very common in Hebrew.

More examples:

• זמן לשאלה = time for a question
• מקום לפגישה = a place for a meeting
• הזמנה למסיבה = an invitation to a party

Notice that the ל־ is attached directly to the noun.

Because the phrase is indefinite: it means a fixed day for a meeting / for the meeting, not necessarily the fixed day.

Hebrew marks definiteness with ה־.

Compare:

• יום קבוע = a fixed day
• היום הקבוע = the fixed day

And:

• פגישה = a meeting
• הפגישה = the meeting

If the sentence wanted to say the fixed day for the meeting, it would look different, for example:

• יש לנו היום הקבוע לפגישה

In your sentence, the speaker is just saying they have some regular day set aside.

In Hebrew, most weekdays are named by number:

• יום ראשון = first day = Sunday
• יום שני = second day = Monday
• יום שלישי = third day = Tuesday
• יום רביעי = fourth day = Wednesday
• יום חמישי = fifth day = Thursday
• יום שישי = sixth day = Friday

Saturday is different:

• שבת = Sabbath / Saturday

So יום רביעי is the standard Hebrew word for Wednesday.

Both are possible in some contexts, but יום רביעי is the full form and is very common.

• יום רביעי = Wednesday
• רביעי by itself can sometimes mean Wednesday, especially when the context is clear

For learners, it is safest to recognize and use the full form first.

Examples:

• אנחנו נפגשים ביום רביעי = We meet on Wednesday
• רביעי לא טוב לי = Wednesday is not good for me

But יום רביעי is clearer and more complete.

Because in present-tense Hebrew, the verb to be is usually omitted.

So Hebrew often says:

• הוא עייף = He is tired
• היא בבית = She is at home
• יום רביעי לא מתאים לי = Wednesday is not suitable for me / Wednesday doesn’t work for me

There is no separate present-tense word for is in ordinary sentences like this.

So literally this part is something like:

• Wednesday not suitable for me

but natural English is:

• Wednesday doesn’t work for me

Literally, מתאים לי means suits me or is suitable for me.

Breakdown:

• מתאים = suitable / fitting / suits
• לי = to me / for me

So:

• זה מתאים לי = That suits me / That works for me
• יום רביעי לא מתאים לי = Wednesday doesn’t suit me / Wednesday doesn’t work for me

This expression is extremely common in Hebrew for schedules, plans, clothes, ideas, and more.

Examples:

• הזמן הזה מתאים לי = This time works for me
• הצבע הזה מתאים לך = This color suits you
• מחר לא מתאים לנו = Tomorrow doesn’t work for us

Because מתאים agrees with the subject, which here is יום רביעי.

• יום is masculine singular
• so the adjective/participle is מתאים (masculine singular)

Compare:

• השעה הזאת מתאימה לי = This hour/time suits me
  (שעה is feminine singular, so מתאימה)

• הימים האלה מתאימים לי = These days suit me
  (plural, so מתאימים)

So in your sentence:

• יום רביעי לא מתאים לי
  because יום רביעי is masculine singular.

Hebrew often puts pronoun phrases like לי (to me / for me) after the main adjective or verb phrase.

So:

• לא מתאים לי = doesn’t suit me / doesn’t work for me

This word order is very natural in Hebrew.

You can think of it as:

• [subject] + [not suitable] + [for me]

Examples:

• זה טוב לי = This is good for me
• הזמן הזה נוח לי = This time is convenient for me
• יום חמישי לא מתאים להם = Thursday doesn’t work for them

Yes, that would be understandable, but doesn’t work for me is usually more natural in this context.

Possible translations:

• Wednesday doesn’t work for me
• Wednesday isn’t good for me
• Wednesday isn’t convenient for me
• Wednesday doesn’t suit me

The most natural choice depends on context:

• for scheduling: doesn’t work for me
• for general suitability: doesn’t suit me

Yes. אבל is the normal Hebrew word for but.

So the whole sentence has this structure:

• יש לנו יום קבוע לפגישה = We have a fixed day for the meeting
• אבל = but
• יום רביעי לא מתאים לי = Wednesday doesn’t work for me

It connects two ideas in contrast:

1. there is a regular meeting day
2. Wednesday is not convenient for the speaker

If you wanted to make the meeting explicitly definite, you could use לפגישה only if the context already makes it definite enough, or more explicitly change the phrasing.

For example:

• יש לנו יום קבוע לפגישה
  = We have a fixed day for the meeting / for a meeting

If you want a clearly definite form with the meeting, you might say:

• יש לנו יום קבוע לפגישה שלנו = We have a fixed day for our meeting
• יש לנו יום קבוע בשביל הפגישה = We have a fixed day for the meeting

Also note that when ל־ is attached to a definite noun with ה־, they combine:

• ל + הפגישה → לפגישה or sometimes with vowel marking understood as la-pgisha

So in unpointed Hebrew, לפגישה can sometimes be ambiguous, and context tells you whether it means for a meeting or for the meeting.

Yes, but it would slightly change the structure.

Your sentence says:

• יום רביעי לא מתאים לי = Wednesday doesn’t work for me

If you use ביום רביעי, that means on Wednesday:

• להיפגש ביום רביעי לא מתאים לי = Meeting on Wednesday doesn’t work for me
• ביום רביעי אני לא יכול = On Wednesday I can’t

So:

• יום רביעי לא מתאים לי focuses on Wednesday as the option
• ביום רביעי... means on Wednesday

Both are natural, but they are used in slightly different sentence shapes.
