igual ADVERB maybe; anyway
Igual as an adverb has some interesting uses. If you really don’t mind about something, you use the phrase me da igual or me es igual:
Me da igual or Me es igual hoy o mañana. Today or tomorrow, I don’t mind.
Colloquially, it can have the meaning maybe:
Igual no lo saben. Maybe they don’t know.
And in South America, especially in countries in the south such as Argentina and Chile, it can mean anyway:
Igual voy, quieras o no. I’m going whether you want me to or not.
