Spanish has two futures, will and would. Both add endings to the whole "to" form, both stress the ending, and both use one set of endings for -ar, -er and -ir alike.
-ía = I / he / she / it / you (formal) would
Note that I jumps in with he, she, it and formal you here, the way it does in some other tenses.
The accent stays on the ía even in the "we" form: bailaríamos.
Iría · No iría · Comería · Comería, pero no tengo tiempo · Transformaría la situación
The will endings are the sounds of haber, without the silent h.
Vamos a bailar · Bailamos más tarde · Vamos a bailar más tarde
All three routes to the future remain available: present with context, ir a, or the future tense proper. The ir a structure is used even more in Spanish than in English.
Spanish has no gets in this sense. Where English says it gets transformed, Spanish says it transforms itself.
Contamina (it contaminates) · Se contamina (it gets contaminated) · Se contaminaría
Nobody thinks the river is responsible for contaminating itself. It is simply the structure that replaces the missing gets.
Not every se or me shifts the meaning. You will often hear me imagino where imagino would do just as well.
Me imaginaría que no quiere ir
Ballerina comes from bailar: the Spanish word for dancer is bailarín.
The same que as what, used to join two clauses together.
Me imaginaría · que · no quiere ir
Me imaginaría que no quiere ir.
