Mou aquesta fitxa.

Mou is the imperative form of the verb moure, which means to move.

So in this sentence, mou means move! when speaking to one person informally.

• moure = to move
• mou = move! / move it!

This is a command, not a statement.

Because it is a command.

In Catalan, as in English, commands often begin directly with the verb:

• Mou aquesta fitxa. = Move this piece.
• Obre la porta. = Open the door.
• Escolta. = Listen.

There is no need to include the subject you, because it is understood.

Aquesta means this.

It is feminine singular, and it agrees with fitxa, which is also feminine singular.

Compare:

• aquest = this (masculine singular)
• aquesta = this (feminine singular)
• aquests = these (masculine plural)
• aquestes = these (feminine plural)

Since fitxa is feminine, Catalan uses aquesta fitxa.

Fitxa can mean several related things depending on context, such as:

• piece
• token
• counter
• game piece
• sometimes card, file card, or record slip

In a sentence like Mou aquesta fitxa, the most natural meaning is usually piece or token, especially in a game, puzzle, or board context.

Yes. Here mou is the informal singular imperative: a command said to one person.

Some related forms are:

• mou = move! (to one person, informal)
• moveu = move! (to more than one person, or formal plural)
• mogui = move! (formal singular)

So Mou aquesta fitxa is the kind of command you would say to one person in an everyday situation.

Catalan often leaves out subject pronouns when they are already clear from the verb form.

So instead of saying Tu mou aquesta fitxa, Catalan normally just says:

• Mou aquesta fitxa.

Including tu would usually add emphasis, contrast, or impatience:

• Tu, mou aquesta fitxa. = You, move this piece.

In neutral speech, the pronoun is usually omitted.

A simple approximate pronunciation for an English speaker is:

mohw ah-KEH-stuh FEET-shuh

A few notes:

• mou sounds roughly like mow in English, though the vowel quality can vary by dialect
• aquesta has the stress on ques: ah-KES-ta
• fitxa is pronounced with tx like ch in English church

So fitxa sounds roughly like FEE-cha.

In normal Catalan, for a direct command, the most natural order is:

• Mou aquesta fitxa.

Putting the object first is possible only in marked or special contexts, for example for emphasis, but it is not the neutral basic order.

So for a learner, the best pattern to remember is:

• Verb + object
• Mou aquesta fitxa.

The period is normal and correct. In Catalan, commands are often written with a period, not necessarily an exclamation mark.

So both of these are possible:

• Mou aquesta fitxa. = neutral instruction
• Mou aquesta fitxa! = stronger or more forceful

The version with a period sounds like a straightforward instruction.

Yes. If the context already makes clear which piece you mean, Catalan could replace aquesta fitxa with a pronoun:

• Mou-la. = Move it.

Here -la means it for a feminine singular noun, because fitxa is feminine.

So:

• Mou aquesta fitxa. = Move this piece.
• Mou-la. = Move it.
