Queasy means feeling slightly sick, or uneasy about something. Feel queasy, a queasy stomach, queasy about the deal.
The physical sense is mild and usually to do with movement or with something eaten. The figurative sense is more interesting: feeling queasy about a decision means an unease you cannot quite argue for, which is why the word turns up in reporting on ethics and money. Note queasiness; and that the word's origin is uncertain, possibly Norse, possibly French.
