It's easy to get hung up on the meanings of words.
I must admit that having meaning is one of their main purposes, but it's not their only purpose.
How about this:
Hey diddle diddle
The cat and the fiddle
The cow jumped over the moon.
The little dog laughed to see such fun
And the dish ran away with the spoon.
I realise that this rhyme may hide a deeper meaning - I'll look it up in a minute* - but if it does have a deeper meaning then it's hidden so completely that I can't begin to guess what it might be.
For all practical purposes the rhyme Hey diddle diddle is just for fun. It presents us with a energetic and baffling chaos that's thoroughly cheering.
...the trouble is, now I'm wondering if I ought to say something deep about post-modernism.
On the whole, though, it's generally better not.
Word To Use Today: hey. Similar words have been used for a long time in many languages. In Old French it was hay, and in Swedish hej. In South Africa hey is used for emphasis at the end of a statement and to ask for something ti be repeated.
*It turns out that there are loads and loads of theories as to the rhyme's hidden meaning - lots of them hinge on cat being short for Catherine - but quite honestly I don't believe any of them.
