三人行，必有我师(焉)

One of the problems I have with measure words that also have different meanings (I knew 封 as to seal/bestow) is that I think I tend to remember the 'normal' meanings because there's less brain works involved and then get caught out by the measure word usage. What I really need is a vocab learning service that tells me how common the different meanings are, so that I can strategically learn the more common ones first... if there's more than three meanings my brain doesn't usually manage to remember all of them unless they're really related (sigh)
