44. CRUCIBLES; Cupels; PIPESTEM TRIANGLE
A 'couple' means 'two': 'a couple of days' = 'two days' A 'few' means (roughly) 3-10; not many: 'a few days' = 'several days' 'A few' can be used for 'two' as well, but it isn't usually more than 8-10.
The short (and rather unhelpful) answer is that while technically, "a couple" does in fact mean two, it is not always used that way in practice and if you ask several native speakers you're likely to get different responses.
two of the same sort considered together; pair. two persons considered as joined together, as a married or engaged pair, lovers, or dance partners: They make a handsome couple. verb (used with object), cou·pled, cou·pling. to fasten, link, or associate together in a pair or pairs.
couple noun (SOME) B1 [ S ] two or a few things that are similar or the same, or two or a few people who are in some way connected: The doctor said my leg should be better in a couple of days.
