invitarían
Invitarían is the conditional form of the Spanish verb "invitar," which means "to invite." Specifically, it is the third-person plural conditional form, corresponding to "they would invite" or "you all would invite" (in the formal plural 'ustedes' sense). The conditional tense in Spanish is used to express hypothetical situations, polite requests, or future actions from a past perspective. Therefore, "invitarían" conveys the idea that a group of people or a formal group would perform the action of inviting, under certain conditions or as a possibility. For example, "Ellos invitarían a sus amigos a la fiesta si tuvieran tiempo" translates to "They would invite their friends to the party if they had time." In this context, the invitation is contingent upon having sufficient time. Similarly, in a polite request, one might say, "¿Nos invitarían a su casa?" which means "Would you invite us to your house?" using the formal plural 'ustedes' which also conjugates as invitarían. The conditional tense adds a layer of politeness or uncertainty to the act of inviting.
