Guardaré el telèfon a la bossa abans de la reunió.

Catalan often drops subject pronouns when the verb ending already makes the subject clear.

• Guardaré already means I will put away / I will keep
• So jo is not necessary

You could say Jo guardaré el telèfon... if you want emphasis, contrast, or clarity, but the neutral version normally leaves it out.

Guardar usually means to keep, to store, to put away, or to save/keep safe.

In this sentence, it does not mean save in the computer-file sense. Here it means something like:

• put away
• put into
• store in
• keep in

So Guardaré el telèfon a la bossa is the natural idea of I’ll put the phone away in the bag.

Guardaré is the future tense: I will keep / I will put away.

It is formed from the infinitive guardar + the future ending -é:

• guardaré = I will keep
• guardaràs = you will keep
• guardarà = he/she/it will keep
• guardarem = we will keep
• guardareu = you all will keep
• guardaran = they will keep

So the sentence is talking about something that will happen later.

Because Catalan normally uses an article with a specific noun, just as English often does.

• el telèfon = the phone

In context, this could refer to a particular phone that is already understood. Depending on the situation, English might say the phone or my phone, but Catalan often does not need to spell out the possession if it is obvious.

Here a introduces the place where the phone will be put.

So:

• a la bossa = in/into the bag

With verbs of putting or moving something somewhere, Catalan often uses a in this kind of structure. If you want to make the idea of inside extra explicit, you can also say:

• dins de la bossa = inside the bag

So Guardaré el telèfon a la bossa is natural, and Guardaré el telèfon dins de la bossa is a slightly more explicit version.

Because bossa is a feminine noun.

• la bossa = the bag
• a + la = a la

The contraction al only happens with a + el:

• a + el = al
• a + la = a la

So:

• al telèfon would be possible if the noun were masculine
• but with bossa, it must be a la bossa

No. If the context already makes it clear whose bag it is, Catalan often leaves out the possessive.

So:

• a la bossa can naturally mean in the bag
• and in context it may be understood as in my bag

If you want to be explicit, you can say:

• a la meva bossa = in my bag

Both are possible; the shorter version is often enough.

Abans de is the normal expression for before when it is followed by a noun or an infinitive.

In your sentence:

• abans de la reunió = before the meeting

You also use abans de before an infinitive:

• abans de sortir = before leaving
• abans de parlar = before speaking

So de is just part of the standard expression abans de.

Because contractions only happen with el, not with la.

• de + el = del
• de + la = de la

So:

• del llibre = of the book
• de la reunió = of the meeting

Since reunió is feminine and takes la, the sentence correctly uses de la reunió.

Yes, reunió is feminine:

• la reunió = the meeting

A useful pattern is that many Catalan nouns ending in -ió are feminine:

• la reunió
• la cançó
• la decisió
• la informació

It is not an absolute rule for every word in the language, but it is a very helpful pattern.

In Catalan, accent marks help show which syllable is stressed, and sometimes they also show vowel quality.

In this sentence:

• guardaré → stress on the last syllable: guar-da-RÉ
• telèfon → stress on the middle syllable: te-LÈ-fon
• reunió → stress on the last syllable: re-u-ni-Ó

So the accents are not optional spelling marks; they are part of correct written Catalan and help with pronunciation.

Yes. The sentence as given is perfectly normal:

• Guardaré el telèfon a la bossa abans de la reunió.

But Catalan can move the time phrase for emphasis or style:

• Abans de la reunió, guardaré el telèfon a la bossa.

Both are correct. The first sounds like a straightforward statement; the second puts more focus on before the meeting.

Bossa usually means bag, handbag, purse, or a similar container, depending on context.

So in this sentence, la bossa could be:

• a handbag
• a purse
• a bag
• possibly another kind of personal bag

If you specifically meant a pocket, Catalan would use a different word:

• butxaca = pocket

So a la bossa means in the bag, not in the pocket.
