frustrating
UK: frʌˈstreɪtɪŋ | US: ˈfrʌstreɪtɪŋ
adj. causing feelings of annoyance, disappointment, or dissatisfaction
vt. (present participle of frustrate) preventing someone from achieving a goal or fulfilling a desire
The root frustrat comes from Latin frustratus (past participle of frustrare, meaning "to deceive or disappoint"). It entered English via Old French frustrer. The -ing suffix turns the verb into an adjective, describing an ongoing or persistent state. The word originally implied deliberate obstruction but now broadly denotes any hindrance or vexation.
