…and here’s another thing.  This occurred to me after ruminating that eskimos have over 30 words for “snow”.  Likewise, and equally apocryphally, Bedouin Arabs have huggins of words for “sand”.

It comes from the fact that if snow and sand is all you’ve got to look at all day, you’ll rabbit on about it in fine distinctions, rather like the numpties who can discern differences between Coronation Street, Eastenders, Emmerdale Farm and Compact.

So by the same token, how many words must dolphins have for “sea”?
