rubbery
UK: ˈrʌbəri | US: ˈrʌbəri
adj. having the texture or elasticity of rubber; flexible and resilient
adj. (informal) overly smooth or insincere in manner
The word "rubbery" combines "rubber," referring to the elastic material derived from the sap of rubber trees (from the verb "to rub," originally meaning to erase pencil marks with rubber), and the suffix "-y," which turns nouns into adjectives. The term evolved to describe both physical properties (flexibility) and metaphorical traits (artificial smoothness).
