decidirían

Decidirían is the third-person plural form of the Spanish verb decidir in the conditional simple mood. It translates as “they would decide” or “you all would decide” and is used to express actions that would occur under hypothetical conditions, or to discuss possible decisions by a group.

Morphology and usage: Decidirían is formed from the infinitive decidir by adding the thematic vowel and the conditional ending -ían. The accent on the í marks the stress, in keeping with Spanish orthography for syllables ending in -rían. This form typically accompanies plural subjects such as ellos, ellas, or ustedes. It is commonly used in si-clause contexts or in statements about likely or hypothetical choices, for example: Ellos decidirían entre las opciones si tuvieran más información. ¿Qué decidirían ustedes si les presentaran esa evidencia?

Examples and nuances: In everyday use, decidirían helps frame outcomes that depend on conditions. It distinguishes from the future tense (decidirán) by signaling hypotheticals rather than certainties. Because it is a conditional mood, it often appears in subordinate clauses or in polite or cautious discourse when outlining potential actions.

Etymology: Decidiría derives from the verb decidir, which comes from the Latin decidere, meaning to cut off or to determine. The sense has evolved to mean to make a choice or determine a course of action.
