Always Masculine

Even though it refers to things that might seem feminine (like a 'dieta' or 'revista'), the word 'suplemento' always uses 'el' or 'un' because it ends in 'o'.

Using 'de' for detail

To specify what the extra is for, simply use 'de' right after the word, like 'suplemento de equipaje' (luggage supplement).

Noun and Adjective pairing

When describing what kind of supplement it is, the adjective usually follows the noun, such as 'suplemento dietético'.

Don't confuse with 'complemento'

Mistake:Tengo un complemento de diez euros.

Correction: Tengo un suplemento de diez euros.

complemento

/kom-ple-MEN-toh//kompleˈmento/

nounA2general
Use 'complemento' for an item that completes or enhances something else, such as an accessory to an outfit or an addition to a salary.
A stylish leather handbag, a pair of sunglasses, and a colorful scarf laid out on a clean surface.

Examples

Llevo un collar rojo como complemento.

I'm wearing a red necklace as an accessory.

Este bolso es el complemento ideal para tu vestido.

This bag is the perfect accessory for your dress.

Recibió un complemento salarial este mes.

He received a salary supplement this month.

One word, many 'additions'

In English, we use different words for a 'necklace' (accessory), 'extra pay' (bonus), and a 'direct object' (grammar). In Spanish, 'complemento' covers all these 'extra pieces' that finish or complete something else.

Grammar without the jargon

In school, you'll hear 'complemento directo.' This simply refers to the thing or person that receives the action in a sentence, like 'the book' in 'I read the book.'

Don't just say 'Accesorio'

Mistake:Only using 'accesorio' for fashion.

Correction: Use 'complemento' frequently! While 'accesorio' is correct, Spanish speakers often prefer 'complemento' when talking about things that 'complete' an outfit.

apéndice

nounB2academic/formal
Use 'apéndice' specifically for extra material added at the end of a book or document, like an appendix.

Examples

Puedes ver la lista completa en el apéndice del libro.

You can see the full list in the book's appendix.

Suplemento vs. Complemento

Learners often confuse 'suplemento' and 'complemento'. Remember that 'suplemento' typically refers to an extra charge or a vitamin, while 'complemento' is more about an addition that enhances or completes, like an accessory or a salary bonus.
