na-adjective
materialistic; worldly-minded; uncultured
Describes a person or attitude that is overly concerned with money, status, or worldly pleasures, and lacking in refinement or higher ideals.
彼は俗物的な考え方をする人だ。
He is a person with a materialistic way of thinking.
そんな俗物的な発言は控
You should refrain from such worldly-minded remarks.
物質主義的 is a more formal and direct term for 'materialistic', often used in philosophical or economic contexts, whereas 俗物的 carries a stronger nuance of being uncultured or vulgar.
Derived from 俗物 (worldly person, philistine) + the adjectival suffix 的 (-like, -ish). The base 俗物 is a Sino-Japanese compound of 俗 (vulgar, worldly) and 物 (thing, person).
