The smallest amount or degree; the tiniest or most minimal possible.
From Old English 'sliht' (smooth, smooth-haired), evolving to mean 'thin' or 'of little importance.' The '-est' suffix makes it a superlative form.
Originally 'slight' meant smooth or thin (like a slight person), and from that came the idea of something being minor or insignificant—thin things don't weigh much!
