Grammar Rule in 30 Seconds

Use 'on' after 'depend' and 'rely' to show that one thing is decided by or needs another.

  • Always use 'on' after depend, never 'of' or 'from'. Example: 'It depends on the weather.'
  • Use 'rely on' when you trust someone or need them for help. Example: 'I rely on my alarm.'
  • When followed by a verb, use the -ing form. Example: 'Success depends on working hard.'
Subject + 🔗 (depend/rely) + ON + 📦 (Object)

Overview

¿A quién llamas cuando se te apaga el celular en medio de una ciudad nueva o se te corta el Wi-Fi durante una partida importante de videojuegos?
Todos tenemos cosas y personas que necesitamos para pasar el día. Quizás sea esa taza gigante de café por la mañana. O tal vez sea tu mejor amigo que siempre escucha tus quejas.
En inglés, cuando hablamos de necesitar a alguien o algo para que funcione correctamente o para que nos ayude, usamos el phrasal verb rely on. Es una de esas frases 'pegamento' que mantienen unidas tus conversaciones diarias. Piénsalo como la versión verbal de una red de seguridad.
Ya sea que estés hablando de que tu conductor de Uber encuentre tu casa o de que tu laptop aguante una clase de tres horas, rely on es tu expresión ideal. Es simple, es poderosa y, sinceramente, la usamos mucho más de lo que nos damos cuenta. Si no puedes imaginar tu vida sin tus listas de reproducción de Spotify, entonces rely on (confías/dependes de) ellas para tu estado de ánimo.
Si necesitas tu despertador para levantarte para esa clase de las 8 AM, entonces rely on (confías/dependes de) él para que suene fuerte. Se trata de confianza y necesidad.

How This Grammar Works

Este punto gramatical es un 'phrasal verb'. Suena elegante, pero solo significa un verbo (rely) más una pequeña palabra llamada preposición (on). Juntos, crean un nuevo significado que es diferente de la palabra 'rely' por sí sola.
De hecho, en el inglés moderno, casi nunca verás rely sin su mejor amigo on. Son básicamente un paquete, como Netflix y relax. El verbo rely se comporta como cualquier verbo regular.
Lo cambias según quién realice la acción y cuándo la realice. La parte on nunca cambia. Se queda exactamente donde está.
Puedes rely on (confiar en/depender de) una persona (como tu mamá), una cosa (como tu auto) o incluso un sistema (como el autobús público). Es una forma de demostrar que sin esa persona o cosa, podrías estar en problemas. Es la diferencia entre 'Me gusta mi teléfono' y 'Yo rely on (dependo de) mi teléfono para todo'.
¡Uno es una preferencia; el otro es una estrategia de supervivencia!

When To Use It

Usarás rely on en casi todos los aspectos de tu vida moderna. Aquí hay algunos escenarios comunes:

  • Hábitos diarios: 'I rely on caffeine to function before noon'. Muy identificable, ¿verdad?

Preguntas frecuentes (8)

No. While some languages use 'from', English strictly uses `on`. Saying 'depends from' will sound incorrect to native speakers.

They are very similar! `Count on` is slightly more informal and usually refers to people. `Depend on` can be used for people, things, or logical conditions.

Yes, in conversation. If someone asks 'Are you going?', you can simply say `It depends.` It implies that there are conditions you haven't mentioned yet.

Both are used in speech, but `whether` is more formal and grammatically correct for writing. Example: `It depends on whether it rains.`

Absolutely. You can say `The plant depends on sunlight` or `The price depends on the market.`

Adding `heavily` means you need that thing very much. Example: `I rely heavily on my glasses` means you can't see at all without them.

Yes. The adjective form `dependent` also uses `on`. Example: `He is dependent on his inhaler.`

This is likely 'L1 interference.' If your native language (like Spanish or French) uses 'of', your brain tries to translate it directly. You must consciously practice the 'on' connection.
