Etymology: "Signless" is a plain English compound: "sign" combined with the suffix "-less," which means "without" or "lacking." Put together, it describes something that has no sign, mark, or indication of something, such as a signless ink or a signless sky. Because the word is built entirely from two familiar English parts, its meaning follows directly from them. The suffix "-less" has been productive in English since Old English, when it appeared in words like "careless" and "fearless," which is why speakers can form new adjectives like this one on the spot.
