🔄 Contrast Examples
With "razón":
Las razones son el clima y el coste de vida.
The reasons are the climate and the cost of living. (The logical factors.)
With "motivo":
El motivo es que quiero empezar de nuevo.
The motive is that I want a fresh start. (The emotional driver.)
The Difference: 'Razón' lists the objective, logical points you considered. 'Motivo' reveals the deeper, personal desire that pushed you to act.
With "motivo":
El motivo del fracaso fue la falta de comunicación en el equipo.
The reason for the failure was the lack of communication in the team. (The internal human factor.)
With "causa":
La causa del fracaso fue un error en el código.
The cause of the failure was an error in the code. (The direct technical trigger.)
The Difference: You could see the 'motivo' (poor communication) as the underlying problem that led to the 'causa' (the specific code error). 'Causa' is the final domino that fell, while 'motivo' can explain why the dominos were set up that way.

⚠️ Common Mistakes

La causa por la que no te llamé es que se me olvidó.
La razón por la que no te llamé es que se me olvidó.
When giving a personal explanation or excuse, 'razón' is the natural choice. 'Causa' sounds too scientific or detached here.

Frequently Asked Questions
Can 'razón', 'motivo', and 'causa' ever be used interchangeably?
In some very general contexts, yes, but it changes the nuance. For example, 'El motivo/la razón de mi llamada es...' (The reason for my call is...) are both common. However, for scientific facts ('la causa de la enfermedad') or legal motives ('el motivo del crimen'), the specific word is much better.
What's the difference between 'a causa de' and 'por motivo de'?
'A causa de' means 'because of' and points to a direct, often negative, external cause ('El partido se canceló a causa de la lluvia'). 'Por motivo de' means 'for the reason of' or 'on the occasion of' and is more formal, often used for planned events ('La calle está cerrada por motivo del desfile').
