בואו נקשיב לדיילת, כדי שלא נשכח שום פרט חשוב.

Yes, בואו literally means come when speaking to more than one person, but in sentences like this it often works idiomatically as come on, let's...

So בואו נקשיב is not really about physical movement. It means:

Come on, let's listen / Let's listen

A few useful forms:

• בוא = said to one male
• בואי = said to one female
• בואו = said to more than one person

So this sentence is being addressed to a group.

That is very normal in Hebrew.

The form נקשיב is grammatically 1st person plural future: we will listen. But Hebrew often uses that same form to express:

• let's listen
• we should listen
• we're going to listen

So after בואו, the future form naturally gives the sense of a suggestion or invitation:

• בואו נקשיב = Let's listen

This is one of the most common ways Hebrew expresses let's...

The dictionary form is להקשיב = to listen.

So:

• להקשיב = to listen
• נקשיב = we will listen / let's listen

The נ־ at the beginning is part of the future-tense pattern for we.

Because the verb להקשיב requires the preposition ל־ = to.

So Hebrew says:

• להקשיב למישהו / למשהו = to listen to someone / something

That is similar to English, which also uses listen to.

So:

• נקשיב לדיילת = we'll listen to the flight attendant

You would not use את here, because את marks a direct object, and להקשיב does not take a direct object.

In Hebrew, when the preposition ל־ joins the definite article ה־, they combine.

So:

• ל + ה + דיילת becomes לַדיילת

In everyday unpointed Hebrew writing, that usually appears simply as:

• לדיילת

That means the spelling לדיילת can be ambiguous in writing:

• לְדיילת = to a flight attendant
• לַדיילת = to the flight attendant

Without vowel marks, both are written the same way. Context tells you which meaning is intended.

דיילת is the feminine form of flight attendant.

Related forms:

• דייל = male flight attendant
• דיילת = female flight attendant

So this sentence specifically refers to a female attendant. If it were a male attendant, Hebrew would use לדייל.

כדי means so that, in order to, or for the purpose of.

When Hebrew wants a negative purpose, it often uses:

• כדי שלא... = so that ... not / so that ... won't

So:

• כדי שלא נשכח = so that we don't forget / so that we won't forget

It introduces the purpose of listening to the flight attendant.

Because שלא here is part of a subordinate clause after כדי.

You can think of it as:

• ש־ = that
• לא = not

Together, שלא often means something like:

• that ... not
• so that ... not

So:

• כדי שלא נשכח = so that we won't forget

Using only לא here would sound wrong in standard Hebrew.

Because after כדי שלא, Hebrew normally uses the future to describe the intended result.

So:

• נשכח literally = we will forget
• כדי שלא נשכח = so that we won't forget

Even though English may sometimes say so that we don't forget, Hebrew still uses the future form naturally in this structure.

שום means any in negative contexts, and sometimes it gives the sense of not even one.

So:

• שום פרט חשוב = any important detail
• in context: so that we don't forget any important detail

This word is very common with negation:

• לא ראיתי שום דבר = I didn't see anything
• לא שכחנו שום פרט = We didn't forget any detail

So here it fits perfectly after שלא נשכח.

Because in Hebrew, adjectives usually come after the noun they describe.

So:

• פרט חשוב = important detail
  • פרט = detail
  • חשוב = important

The adjective also has to agree with the noun in gender and number.

Here both are masculine singular:

• פרט = masculine singular
• חשוב = masculine singular

If the noun changed, the adjective would change too.

It means any important detail, not every important detail.

That is an important distinction:

• שום פרט חשוב = any important detail in a negative setting
• כל פרט חשוב = every important detail

So the sentence is saying that listening will help us avoid forgetting even one important detail.

The speaker includes themself and invites the group to act together.

So the meaning is:

• you all and I — let's listen

That is why Hebrew uses the we form נקשיב, even though the command word בואו is addressed to you plural. It is an invitation to shared action.
