anxious

the word "anxious" entered english in the early 17th century from latin anxius, meaning "troubled, uneasy." this latin term itself derives from the verb angere, which means "to choke, squeeze, torment, or cause distress." the root of angere can be traced further back to the proto-indo-european base angh-, signifying "tight, painfully constricted." the semantic journey is clear: from a physical sensation of constriction and choking, the meaning evolved to describe a mental state of distress and worry. the modern english usage retains this core sense of mental unease while also developing a secondary, more positive meaning of eager desire, implying a similar internal pressure or tension.

the word is a simplex unit derived from latin, and its modern english spelling does not allow for a clean segmentation into meaningful substrings based on its current form.
