qepHom 2015: It seems like 'echlet is a general term for boards, like keyboard and gaming board, and apparently any flat shaped form. Could I use it for a cutting board? Yes, just like the cutting knife pe'meH taj, this would be a pe'meH 'echlet. What do you see as a size limit? What if I use a construction plate that is six by six feet wide, is that still a 'echlet? It is, but that's weird. If you call that an 'echlet, people would understand, but there's probably another word for something that big. A big slab of concrete under the building, the foundation, that's definitely not an 'echlet. What about, for instance, wooden boards or planks used for wall or ceiling covering, which are few inches wide but several feet long? When it's used by itself, when you use it as part of a construction, there may be another name for it, but the shape itself may be described as 'echlet tIq.
