Common in culinary contexts.
Use 'alt' for something that has existed for a long time (e.g., 'ein altes Haus' = an old house) and 'neu' for something recent (e.g., 'ein neues Auto' = a new car). Avoid confusion with 'frisch' (fresh), which implies recentness in a different way.
As an adjective, 'alt' must be declined based on gender, number, and case. Example: 'ein alter Mann' (masculine nominative), 'die alte Frau' (feminine nominative), 'das alte Haus' (neuter nominative), 'die alten Bücher' (plural nominative).
From Middle High German *alt*, from Old High German *alt*, from Proto-Germanic *aldaz*, from Proto-Indo-European *h₂el- ("grow, nourish"). Cognates include English *old*, Dutch *oud*, Swedish *gammal*, and Latin *altus* ("high").
1. 'Alt' is used for both people and objects, but context determines whether it implies 'aged' (positive, e.g., wine) or 'outdated' (negative, e.g., technology). 2. In formal writing, 'betagt' may replace 'alt' for elderly people. 3. For objects, 'gebraucht' (used) is often preferred in commercial contexts.
