How to Say "pact" in Spanish
The most common Spanish word for “pact” is “trato” — use 'trato' for a less formal, often personal 'deal' or agreement, like a bargain or a promise between individuals.

Gender Check
Remember that 'pacto' is a masculine noun, so it always uses the masculine article: 'el pacto' or 'un pacto'.
Pacto vs. Impacto
Mistake: “Using 'impacto' when you mean 'pacto'.”
Correction: They sound similar, but 'impacto' means 'impact' or 'shock,' while 'pacto' is a formal 'agreement' or 'deal'.
convenio
kon-BEH-nyohkomˈbenjo

Examples

The collective agreement will improve working conditions.

Always Masculine
Even though it refers to an 'agreement' (which is feminine 'la alianza' in some contexts), 'convenio' is always masculine: 'el convenio' or 'un convenio'.
Formal Tone
Use 'convenio' when talking about written or legal documents. For a casual spoken agreement with a friend, use 'acuerdo' instead.
False Friend Alert
Mistake: “Using 'convenio' to mean 'convenience'.”
Correction: Use 'conveniencia' for 'convenience'. 'Convenio' is strictly a formal agreement.
alianza

Gender Check
Remember that 'alianza' is a feminine noun, so you must use feminine words like 'la' or 'una' before it: 'La alianza es importante'.
tratado
trah-TAH-dohtɾaˈtaðo

Examples
