The use of latin doesn't help either. "Cytoplasmic net" (or better yet "plasma net") is a lot easier to understand, visualise and remember than "endplasmic reticulum".
If you are an English speaker. If you are native in a Latin-based language, "reticulum" is pretty clear (reticolo, retículo, réticule etc). So, it's just a point of view and dictaded by the most used language within research/education at a particular point in time.
