rub
This word evokes a tactile sensation of friction and pressure. It is most commonly used to describe physical contact that generates heat or removes a substance, carrying a neutral to positive connotation when referring to massage or skincare, but a negative one when describing irritation or wear and tear. When used as a noun to describe a problem, it functions as a specialized idiom meaning a catch or a snag. This usage is more formal or literary than the physical act of rubbing and typically appears in the phrase "there is the rub."
