Ir/venir + gerundio (gradual action)

The constructions ir + gerundio and venir + gerundio are verbal periphrases that frame an action as unfolding gradually or accumulating over time. Ir + gerundio presents a process as developing step by step, often toward a future endpoint — the focus is on forward movement through stages. Venir + gerundio presents a process that has been running continuously up to the present moment — the focus is on the accumulated duration leading to now. Both constructions differ fundamentally from the simple progressive (estar + gerundio), which describes an action at a single point in time rather than its gradual trajectory.

• Gradual, incremental development (ir + gerundio). Use this when a situation changes little by little over time, especially when you want to highlight the step-by-step nature of the change. It is common with adverbs such as poco a poco, lentamente, or cada vez más.

• A process that has been going on up to now (venir + gerundio). Use this when you want to stress that something has been happening continuously or repeatedly from a past point right up to the present. It often appears with time expressions such as desde hace meses or desde enero.

• Narrating a historical or past trend (ir + gerundio in the preterite or imperfect). When recounting how a situation evolved over a past period, ir is conjugated in the preterite (for a completed trend) or the imperfect (for an ongoing background trend).

• Idiomatic alternative to «more and more». Where English uses «more and more + adjective/verb», Spanish often prefers ir + gerundio (combined with cada vez más if needed) rather than a literal adverb pile.

The structure is: a conjugated form of ir or venir + the gerund of the main verb. The auxiliary carries tense, aspect, mood, and agreement; the gerund is invariable.

Gerund formation follows the standard rules: -ar verbs → -ando; -er/-ir verbs → -iendo (with the usual stem-vowel changes for irregular verbs, e.g. decir → diciendo, venir → viniendo).

• Using the infinitive instead of the gerund. The auxiliary must be followed by a gerund, not an infinitive. *fue empeorar is not Spanish; the correct form is fue empeorando. If you find yourself writing an infinitive after ir or venir in this construction, change it to the -ando/-iendo form.

• Confusing ir a + infinitive with ir + gerundio. These are two entirely different periphrases. Voy a entender means «I am going to understand» (a future plan or intention). Voy entendiendo means «I am gradually coming to understand» (a process already in progress). The presence or absence of a — and the infinitive vs. gerund — completely changes the meaning.

• Piling up adverbs to render «more and more». A direct translation of «I understand more and more» as *entiendo más y más sounds unnatural. The idiomatic Spanish option is voy entendiendo (or voy entendiendo cada vez más for added emphasis). Reserve cada vez más for when you need to make the increasing degree explicit; ir + gerundio alone already carries the gradual-progress meaning.
