Is the usage of the word couple (as in, "I want to ask a couple of questions...") to mean 'some' or 'few' correct (as in, interpreting given example to mean "I want to ask a few questions")?
As a follow-up on the example, when someone says "I want to ask a couple of questions...", does the usage of 'couple' necessarily mean the two questions have to be related to each other, or can couple just mean 'two' in that context?
