old

The word 'old' descends directly from the Proto-Germanic aldaz, which itself evolved from the Proto-Indo-European root al-, meaning 'to grow, nourish'. This foundational concept of growth is key, as 'old' inherently describes the result of having grown for a long time. In Old English, it took the forms 'eald' (West Saxon) and 'ald' (Anglian), used to describe people, objects, and times long past. Through the regular sound changes of English, notably the loss of the initial vowel in some dialects and the simplification of the consonant cluster, the word streamlined into its modern form 'old', retaining its core semantic link to advanced age and antiquity.

This is a simplex word of Germanic origin. The root is the Old English 'eald' or 'ald', meaning 'aged, ancient, antique'. It functioned as a core adjective.
