different between nervous vs unsure

English

Etymology

From Middle English nerv?us (“containing nerves; made up of nerve-like fibres; of or relating to nerves; containing sinews or tendons, sinewy; affecting sinews or tendons”), from Latin nerv?sus (“nervous; sinewy; energetic, vigorous”), from nervus (“nerve; muscle; sinew, tendon; (figuratively) energy, power; nerve; force, strength, vigour”) (ultimately from Proto-Indo-European *snéh?wr? (“sinew, tendon”)) + -?sus (suffix meaning ‘full of, prone to’ forming adjectives from nouns). The English word is analysable as nerve +? -ous.
