deep-rooted

The compound adjective 'deep-rooted' is a transparent metaphorical extension from the literal botanical world into abstract social and psychological domains. Its first element, 'deep', originates from the Proto-Germanic deupaz, conveying profound physical or abstract depth. The second element, 'root', descends from Proto-Germanic wrōts, denoting the foundational, anchoring part of a plant. The suffix '-ed' attaches to the noun phrase 'deep root' to form an adjective meaning 'characterized by having deep roots'. The term's logic is vividly illustrative: just as a plant with deep roots is stable and hard to remove, so a tradition, habit, or problem that is deep-rooted is firmly entrenched and resistant to change.
