Etymology
The word 'lair' originates from the Old English 'leger', meaning a bed, a couch, or a place where one lies down. This Old English term is derived from the Proto-Germanic 'legrą', which is rooted in the Proto-Indo-European base 'legh-', meaning 'to lie down'. The semantic journey from a general resting place to its modern meaning is clear: it first specialized to refer to the resting or dwelling place of an animal. Over time, it acquired connotations of secrecy and concealment, extending metaphorically to describe a hidden refuge or den for people engaged in covert activities.
Analysis
The word 'lair' is a simplex word of Old English origin. It does not break down into smaller, meaningful morphemes within its modern English spelling.
