affected by physical or mental illness
nursing very sick children
half my staff were off sick
visiting the sick and the elderly
feeling nauseous and wanting to vomit
he was starting to feel sick
Mark felt sick with fear
intensely annoyed with or bored by (someone or something) as a result of having had too much of them
I'm absolutely sick of your moods
very good; excellent
it was a sick party and there were tons of cool people there
