Salirse por la tangente

to dodge the question; **to dodge the question**; **to evade the issue**; **to sidestep the question**; **to go off on a tangent**

Salirse por la tangente means to avoid answering a question directly by changing the subject, giving an irrelevant reply or steering the conversation away from the main issue.

The speaker deliberately avoids confronting the point being discussed.

The expression often suggests evasion rather than simple distraction.

• avoids answering a difficult question
• changes the subject
• gives an indirect or irrelevant reply
• refuses to address the real issue
• tries to escape an uncomfortable conversation

The expression comes from geometry.

A tangent touches a curve at a single point and then immediately moves away instead of continuing through it.

This image became a metaphor for conversations in which someone briefly approaches the subject before quickly moving away from it.

The geometric origin remains clearly visible in the modern expression.

Spanish speakers often use this idiom when they suspect deliberate avoidance.

It usually carries a mildly critical tone.

Someone who se sale por la tangente is often seen as unwilling to give a clear or honest answer.

This is one of the few everyday Spanish idioms whose origin can be traced directly to mathematics.

Most speakers have forgotten the geometric image.

Yet every time someone avoids a difficult question, Spaniards still say:

Se ha salido por la tangente.

Without realising it, they are describing the conversation with the language of geometry.

Do not translate the expression mechanically.

Although English also has:

to go off on a tangent

the meanings are not always identical.

In many contexts, the better translation is:

• to dodge the question
• to evade the issue
• to sidestep the question

Always consider whether the speaker is changing the subject accidentally or intentionally.
