Gradual progress (ir, venir + gerund)

Little by little: Ir + gerund

To describe an action that is developing slowly or step-by-step, Spanish uses the verb ir (to go) followed by a gerund (verb forms ending in -ando or -iendo).

This structure, ir + gerund, emphasizes that a process is moving forward gradually. In English, it often translates to "is gradually doing" or "is doing little by little".

Building up to now: Venir + gerund

When an action started in the past and has been slowly building up to the present moment, use the verb venir (to come) + gerund.

While ir + gerund focuses on an ongoing progression moving forward, venir + gerund focuses on what has accumulated up to now. It often translates to "has been doing".
