אם נקצר את הפגישה יותר מדי, לא נספיק לשאול על המזרן, על הפיקדון ועל כל רהיט קטן.

Because the sentence is talking about we: if we shorten the meeting too much, we won’t have enough time...

In Hebrew, both verbs are in 1st person plural future:

• נקצר = we will shorten
• נספיק = we will manage / we will have enough time

This is very common in Hebrew conditional sentences about future situations.

In Hebrew, אם means if, and when the sentence refers to a possible future situation, Hebrew often uses the future tense in both parts:

• אם נקצר... = if we shorten...
• לא נספיק... = we won’t manage...

This is different from English, where we usually say If we shorten..., not If we will shorten....
So Hebrew allows future forms here where English normally uses present in the if clause.

את marks a definite direct object.

Here:

• נקצר את הפגישה = we will shorten the meeting

Because הפגישה means the meeting and is definite, Hebrew uses את before it.

A helpful rule:

• definite direct object → usually needs את
• indefinite direct object → usually no את

For example:

• קראתי את הספר = I read the book
• קראתי ספר = I read a book

יותר מדי literally means something like more than enough, and in normal usage it means too much or overly.

So:

• נקצר את הפגישה יותר מדי = we shorten the meeting too much

Even though לקצר means to shorten, the phrase יותר מדי still works naturally with it, just like English too much:

• shorten it too much
• talk too much
• eat too much

The verb להספיק means to be enough, to suffice, or very often to have enough time / manage to.

In this sentence:

• לא נספיק לשאול... = we won’t have enough time to ask...
• or more literally: we won’t manage to ask...

This verb is extremely common in spoken Hebrew.

Examples:

• אני לא אספיק = I won’t have enough time
• הספקת? = Did you manage? / Did you have enough time?
• נספיק להגיע בזמן = We’ll manage to arrive on time

Because להספיק is followed by another verb in the infinitive, much like English manage to do or have time to do.

So:

• נספיק לשאול = we’ll have time to ask
• לא נספיק לשאול = we won’t have time to ask

This pattern is very common:

• הוא הספיק לאכול = he managed to eat
• לא הספקנו לראות = we didn’t have time to see

Because לשאול על means to ask about.

So:

• לשאול על המזרן = to ask about the mattress
• לשאול על הפיקדון = to ask about the deposit

Compare:

• לשאול על משהו = to ask about something
• לשאול מישהו = to ask someone
• לשאול משהו ממישהו = to borrow something from someone

So the preposition changes the meaning.

Repeating the preposition is very natural in Hebrew, and often clearer.

So Hebrew prefers:

• על המזרן, על הפיקדון ועל כל רהיט קטן

rather than leaving על only once at the beginning.

English can often say about the mattress, the deposit, and every small piece of furniture, but Hebrew commonly repeats the preposition with each item in a list, especially in careful or clear speech.

Grammatically, פיקדון is a masculine noun. In this sentence it means something like a deposit, especially in a rental or financial context.

With the definite article:

• הפיקדון = the deposit

This is a useful word in apartment, rental, or contract conversations.

Because כל often means every, and after כל, Hebrew commonly uses a singular noun:

• כל רהיט קטן = every small piece of furniture

This is normal Hebrew grammar.

More examples:

• כל יום = every day
• כל ילד = every child
• כל דבר קטן = every little thing

So even though English may think in a more collective way, Hebrew naturally uses the singular after כל.

רהיט is a piece of furniture / an item of furniture.
The plural is רהיטים = furniture items / pieces of furniture.

That matters because English furniture is usually an uncountable noun, but Hebrew often uses a countable noun:

• רהיט = one item of furniture
• רהיטים = furniture items

So כל רהיט קטן is very natural Hebrew for every little piece of furniture.

The sentence as written is very natural, but Hebrew word order is somewhat flexible.

Current order:

• אם נקצר את הפגישה יותר מדי, לא נספיק לשאול...

This is the most straightforward structure:
if-clause first, then the result.

You could also reverse the order in some contexts:

• לא נספיק לשאול על המזרן, על הפיקדון ועל כל רהיט קטן אם נקצר את הפגישה יותר מדי.

That is still grammatical, but the original version sounds more natural in most everyday situations.

The base form is לקצר, which means to shorten.

So the forms are:

• לקצר = to shorten
• נקצר = we will shorten
• קיצרנו = we shortened
• מקצרים = shortening / shorten

This verb is commonly used for making something shorter, such as:

• לקצר את הפגישה = to shorten the meeting
• לקצר את הדרך = to shorten the route
• לקצר את השיחה = to shorten the conversation

It is mostly neutral standard Hebrew and sounds completely natural.

Nothing in it is especially slangy or literary. A native speaker could say it in everyday conversation, especially in practical contexts like organizing a meeting, discussing an apartment, or planning what to ask.

The structure is also a good example of standard Hebrew grammar:

• אם + future
• לא + future
• להספיק + infinitive
• repeated prepositions in a list
