"ir" and "acudir"
How are these two verbs different?
2 Answers
Acudir is more sophisticated and abstract; ir is more common and concrete. Again I would recommend you reading some real usage scenarios on Linguee.com
Ir means to go (with or without an invitation or a request or a summon)
Acudir means to go to the rescue, attend to or respond to an invitation, order or request.
