Demà preparem un viatge a la ciutat amb un mapa sobre la taula.

Demà means tomorrow. In Catalan, just like in English, a time expression can go at the beginning of the sentence to set the time frame first.

So:

• Demà preparem... = Tomorrow we prepare...

This word order is very natural. You could also place demà later in some contexts, but putting it first is very common.

Catalan often drops the subject pronoun when the verb form already makes the subject clear.

Here, preparem means we prepare. The ending -em shows that the subject is nosaltres (we), so Catalan does not need to say nosaltres unless you want emphasis or contrast.

• Preparem = we prepare
• Nosaltres preparem = we prepare (with extra emphasis)

Preparem is the 1st person plural form of the verb preparar (to prepare / to plan / to get ready depending on context).

Its basic present-tense pattern is:

• jo preparo = I prepare
• tu prepares = you prepare
• ell/ella prepara = he/she prepares
• nosaltres preparem = we prepare
• vosaltres prepareu = you all prepare
• ells/elles preparen = they prepare

So in this sentence, preparem means we prepare.

Grammatically, preparem is present tense. But Catalan, like English, often uses the present to talk about a scheduled or intended future action, especially when a time word makes the future clear.

So:

• Demà preparem un viatge... literally uses the present
• but it can be understood as Tomorrow we’re preparing / we prepare / we will prepare...

The word demà already tells you the action is in the future.

Un is the masculine singular indefinite article, meaning a or an.

• un viatge = a trip

Catalan usually uses an article here just as English does. Since viatge is a singular countable noun, un is the normal choice.

You can tell from the article:

• un viatge → masculine singular

If it were feminine, you would expect una.

Gender in Catalan is partly predictable, but often it must simply be learned with the noun. So it is best to memorize nouns together with their article:

• el viatge = the trip
• un viatge = a trip

Here a means to or toward, depending on context.

• a la ciutat = to the city

Catalan commonly uses a to mark direction or destination. Since ciutat is feminine singular, la is the correct article:

• la ciutat = the city
• a la ciutat = to the city

In Catalan, a + el contracts, but a + la does not.

So:

• a + el = al
• a + la = a la

Examples:

• al poble = to the town
• a la ciutat = to the city

That is why the sentence has a la ciutat, not a contraction.

Amb usually means with.

Here it introduces un mapa:

• amb un mapa = with a map

This can describe the means, accompaniment, or a detail connected with the action. In practical terms, it tells us that the trip-planning involves a map.

The most natural reading is that sobre la taula describes un mapa:

• amb un mapa sobre la taula = with a map on the table

So the image is that the map is on the table while the planning is happening.

In theory, prepositional phrases can sometimes create ambiguity, but in this sentence most learners would understand sobre la taula as attached to mapa.

Here sobre means on or on top of.

• sobre la taula = on the table

Catalan often uses sobre for physical location on a surface. In some contexts, damunt de can also be used for on top of, but sobre is very common and natural here.

A comma after an initial time expression is usually not necessary in Catalan when the sentence is short and straightforward.

So:

• Demà preparem un viatge... is perfectly normal

A comma might appear in some writing styles for emphasis or rhythm, but the version without a comma is standard and natural.

Yes, that is possible. Catalan allows some flexibility in word order.

• Demà preparem un viatge...
• Preparem un viatge demà...

Both are grammatical, but starting with demà puts more focus on the time.

Ciutat is pronounced roughly like see-oo-TAT in Central Catalan, though the exact vowel quality depends on dialect.

A few useful points:

• ci here sounds like s
  • vowel
• the ending stress falls on -tat
• the written u is part of the normal spelling of the word

You do not need to pronounce every letter exactly as an English speaker would expect from the spelling; Catalan spelling follows its own sound patterns.

That depends on context and on the meaning already provided to the learner. Grammatically, preparar un viatge most directly means to prepare/plan a trip.

If you wanted to express prepare for a trip, Catalan would often use a different structure, such as one involving per a or another wording depending on the exact meaning.

So the sentence as written is most naturally understood as planning or preparing the trip itself.

A learner may find it helpful to break the sentence into chunks:

• Demà = tomorrow
• preparem = we prepare
• un viatge = a trip
• a la ciutat = to the city
• amb un mapa sobre la taula = with a map on the table

Seeing these blocks makes the sentence easier to understand and helps with word order.
