Echar leña al fuego

to add fuel to the fire; **to add fuel to the fire**; **to pour oil on the fire** (less common in English than in some other languages); **to make matters worse**; **to inflame the situation**

Echar leña al fuego means to make a bad situation worse, intensify a conflict or provoke even more tension.

The expression implies that the problem was already serious before someone made it worse.

• says something that increases an argument
• worsens an already difficult situation
• provokes people who are already angry
• spreads rumours that create more conflict
• deliberately increases tension

The expression comes directly from everyday experience.

Adding more wood to a burning fire makes the flames larger and more intense.

Spanish transferred this obvious physical effect to human conflicts, where words or actions can make disagreements grow instead of disappear.

The metaphor is immediately understood by native speakers.

The expression is often used as advice:

No eches leña al fuego.

It encourages people to calm a situation rather than intensify it.

For this reason, it frequently appears in family arguments, workplace conflicts and political debates.

Fire is one of the most productive sources of metaphors in Spanish:

• Echar leña al fuego → to add fuel to the fire.
• Jugar con fuego → to play with fire.
• Apagar un fuego → to solve an urgent problem.

The image of fire naturally lends itself to describing emotions, arguments and dangerous situations.

This expression has an almost perfect English equivalent.

Translate it as:

• to add fuel to the fire

or, depending on the context:

• to make matters worse
• to inflame the situation

Avoid translating leña literally as wood.

The established English idiom uses fuel.
