'Fiddler'

  Previously, the best available translation of this 
  word was settler. It’s a good attempt, but makes
  no sense in the context. The beginning consonant is 
  definitely an ‘f’.

  The word ‘fettler’ has several meanings that
  would have been very familiar in the vicinity of 16th 
  Century Glasgow, the most appropriate of which is ‘a 
  part time worker’. 

  However, the word is more likely ‘fiddler’. 
  This term, when used in the context of other seafood 
  (Mackerel) would have brought to mind fiddler crabs. 
  It’s interesting that soldier rations of the day 
  included mackerel and crab. 

  'Rack' 

  This word had multiple meanings in 16th  
  Century Scotland. Assuming this is an 
  account of a great battle, the most 
  appropriate definition is 'rubble
  associated with battle'.

  One common definition of 'rut' for that period is 
  'route' and was typically used in a military context.
  'Rutted' would be in the sense of 'trekked'.

  'hade' 

  'Haem', meaning 'home' was an attempt for
  this word but it clearly ends with a ‘d’ sound;
  not 'm'. In the mining regions, such as the 
  Langside area, a hade was a familiar term meaning 
  sloping land or an area of unplowed land. 
  This will make more sense after seeing item 
  'Furrow'. 

 'Furrow' 

  To date there has been no satisfactory interpretation. 
  The term, if you mentally separate it from the reverb, 
  sounds like ‘furruh’ (with the rolling ‘r’). Now, a 
  furrow is the groove formed by a plow and, in verse, 
  often refers to plowed land. Taken together with ‘Hade’,
  the picture of sloping farmland, plowed and unplowed 
  farmland, comes to focus. Interestingly, Langside was at
  that time surrounded by sloping farmland! Historically,
  Mary’s troops had descended from the “High Road” toward
  Langside as part of a troop maneuver. Thus the phrase 
  “Rutted down by the Hade and the Furrow” makes perfect
  sense. 

 'Slipped Me'

  a construct typical of the day meaning 
  simply “I slipped”. 

 ‘flop’

  A ‘flop’ is the old term for a muddy patch. 

  ‘Hit Down’

  “landed hard”.

  ‘Shied’ was a term meaning, ‘to grow afraid or 
  apprehensive’. The whole picture, then, is of someone 
  slipping and falling down in mud (after all he was 
  walking downhill through farmland) and becoming 
  apprehensive for some reason. 

  Why? -- Because falling down in mud made him think 
  of falling down while in battle but never getting up. 
  Thus “…And I cried, cried, cried, the fear 
  of fallen down aft’, taken never back to rise.” 
  (Shied, cried and rise all have the ‘ai’ 
  sound with the Scottish accent).

  Some interpret the next words to be “And then 
  Craig Marion”. The other suggested interpretation 
  is, “And then cried Mary and…” This interpretation 
  makes much more sense in the context of the lines 
  that follow as will be shown. Evidently, Mary Queen 
  of Scots gives the battle cry and then the troops 
  charge. Either that or the narrator cries out Mary 
  to indicate his allegiance and build courage before 
  charging.

  “Tucked up” is the term that has been mistakenly 
  translated “took that” or “get out”. In the 16th 
  Century, when a peasant soldier in typical garb--a 
  long over-shirt--was ready to charge he would first 
  “tuck up”, which meant that he would put folds in 
  his loose shirt and tuck it under his belt to keep 
  it tight. It was this action and the resulting folds 
  that gave birth to the kilt as part of the traditional 
  Scottish military uniform.

  About – it sounds like he’s saying “Claymore out 
  and abott”. Actually, ‘abotte’ was an alternate 
  spelling/pronunciation of ‘about’ at that time.

  Mechyn Sty in the 16th Century meant “humble path”. 
  History reports that Mary’s troops charged down a 
  small path and into battle. Remember, sty would be 
  pronounced stay with the Scots accent.

  Hore – Filth. Not positive this is what he says, 
  but if this is right, then the narrator runs down 
  to a field, falls in mud, gets up, runs down a 
  little path and then back into filth that surrounds
  his feet. But why would it say ‘back’? Not sure.

  Burnie Brae – A burnie is a smallish river. Brae
  is pronounced like Brew which may be the reason 
  why some have mistakenly interpreted it to be crew. 
  A Brae is a hillside at a crook in a winding river.
  Guess what? There is a street in the Langside area 
  called “Burnie Brae”. Interestingly, “Burnie Brae” 
  is a common place name and street name in Scotland.

 Snapped is synonymous with snatched.

  Feat Deah – “deah” was a common Scottish word 
  meaning “meaningful” or valorous. “Feat” is a 
  deed” So this basically means “deed of valor”. 
  He actually says something like “deah” twice 
  and I haven’t figured out why. Sounds like he 
  got it wrong the first time and then corrected 
  himself.
