Sense: adjective/1
All four words describe something that falls below an acceptable standard, but they differ in scope and formality. 'Worst' is the broadest and most common superlative, covering quality, condition, and personal experience ('the worst meal', 'the worst pain'). 'Poorest' is more specific: it usually refers to workmanship, condition, or financial status ('poorest harvest in decades'), and it carries a stronger connotation of lack or deficiency. 'Lowest' focuses on rank, measurement, or position on a scale ('lowest test score', 'lowest price'), making it more objective and quantitative. 'Inferior' is the most formal and implies a comparative judgment against an expected standard ('inferior materials'); it is less emotional than 'worst'. In everyday speech, 'worst' fits most situations, while 'lowest' suits data or rankings, 'poorest' suits outcomes of effort or resources, and 'inferior' suits formal or technical writing.

Etymology
Old English 'wierresta' or 'wyrresta', the superlative form of 'yfel' (evil, bad). Through Middle English it became 'worste', then 'worst' in modern spelling. The verb sense developed in the 1600s, meaning 'to get the worst of' someone, which later became 'to defeat'.
