I like the expression ‘OK’. I don’t know why. _________________. Everyone in the world understands what it means. It must _________________ that everyone knows. Is it a word or is at an abbreviation? We spell it ‘okay’ _________________ as ‘OK’. I wonder _________________ it has. You can ask if someone is OK, if they are ill; _________________ someone understands a question or instructions using OK; you can even let someone know ‘_________________’ by saying OK. If you say something is OK, it means you don’t really _________________. In fact, sometimes, if you say, “He’s OK” or “She’s OK, it means you don’t really like them. I think okay is also a verb. I have heard people say, “It’s OK, _________________”.
