Think of the words lump and sorts visually. A lump is a mass, a pile or collection of something that creates a form. It can be a physical shape or a mental image. For example, you get hit on the head and you develop a lump, you put a lump of sugar in your coffee, all the papers are lumped together on the desk, you can be paid in a lump sum of money or lump your ideas together at the meeting, To sort is to group together or make a category of things of ideas with similar features or qualities. You sort your clothes into whites or colors before washing, I like all sorts of music, he takes all sorts of medication, people think the politicians tell all sorts of lies and you can research all sorts of information on the internet.
