Smatter comes from Middle English smateren ('to chatter, talk idly, have superficial knowledge'), of uncertain origin, possibly imitative or related to Middle High German smetern ('to chatter, clatter'). The historical chain includes Middle English smateren. Older glosses in the chain include "to chatter, talk idly, have superficial knowledge" and "to chatter, clatter", which help explain the semantic range of the modern word. Morphologically, smatter is best read as borrowing, imitative formation, and uncertain formation, yielding an English verb and noun shaped by both form history and later usage. In current English it functions as a verb and noun, with the sense "to have or talk with only superficial knowledge of something". English derivatives include smattering and smatterer. The result is an English verb and noun whose etymology preserves the older forms while supporting the word's specialized modern meaning.
