Body Parts and Articles

When talking about body systems, Spanish usually uses the definite article 'el' (the) instead of possessives (my/your): 'el aparato digestivo' (the digestive system), not 'mi aparato digestivo'.

dispositivo

dis-poh-see-TEE-voh/disposiˈtiβo/

nounB1general
Choose 'dispositivo' for a general-purpose mechanism or gadget, especially electronic ones.

Masculine Noun Rule

Remember that 'dispositivo' is always used with masculine articles: 'el dispositivo' (the device) or 'un dispositivo' (a device).

Gender Confusion

Mistake: “La dispositivo”

Correction: El dispositivo. Even though it ends in '-o', sometimes learners confuse it with other feminine nouns that end similarly. Always use 'el'.

instrumento

een-stroo-MEN-toh/instɾuˈmento/

nounA1general
Use 'instrumento' when referring to a tool or piece of equipment used for scientific measurement or a specific task.

Gender Check

Even though it ends in 'o', it follows the common pattern: 'instrumento' is always masculine (el instrumento), so use masculine adjectives with it.

máquina

nounA1general
Opt for 'máquina' when the apparatus is a complex device with moving parts, often performing a specific function like sewing or printing.

Examples

Mi abuela todavía usa una máquina de coser muy antigua.

My grandmother still uses a very old sewing machine.

Device vs. System

Learners often confuse 'dispositivo' (a general gadget) with 'aparato' (a system or structure). Remember that 'dispositivo' is for a standalone item, while 'aparato' often implies a connected or integrated set of parts, like a biological system.
