- I think this page really needs either more detail or an example. 'Unit' seems fairly vaugue and unclear. If I understood the definition of the word I would add one myself... but I suppose if I could understand it then there wouldn't be a problem.
- Ran is not a variation of run in the linguistic sense; it is a separate word that has been memorized with its own specific meaning. If the concept of someone running in the past was a direct variation of run then it would be spelled runned, not ran. Ran is an irregular past tense verb and should not be used as an example being that it is its own lexeme.
