  Rhyming "wood" with "flood"
  (from "My heart's in the Highlands" by R. Burns)
  The two words don't rhyme, do they? But they appear in poetry as rhyming. Every time I come across a line ending with "flood" or "blood" and the next one ending with the sound, I feel a bit puzzled. Were such words pronounced differently at the time they were written? If so, do you read them as they should sound taking it from the point of view of the modern language?
  They are not an exact rhyme in modern English, but Robert Burns (1759-96) was a Scottish poet who wrote in the Scots dialect and would recite his work with his native pronunciation.
  I'm sure you can find examples of this dialect on YouTube.
  In Scotland and much of northern England, "wood" and "flood" rhyme. They don't rhyme in RP or in American English.
  Also, you'll find that some rhymes don't work in any modern dialect of English, instead reflecting the pronunciations of older forms of English. An example is rhymes of "prove" and "love", which centuries ago would have both rhymed with "stove".
