So maybe I'm interpreting interactions all wrong but the directionality of effects is confusing me.

Suppose I have an outcome variable "OV" and two explanatory variables "EV1" and "EV2". Now suppose that the main effect of EV1 on OV is positive while the main effect of EV2 on OV is negative.

If I interact EV1 and EV2 together, and the interaction effect is positive, How do I conceptually interpret this direction of effect?

Would it be that because EV1:EV2 is positive, as EV1 increases, the effect of EV2 on OV becomes larger (i.e., more negative)?
