Mechanics refers to the rules that govern written language. Mechanics are conventions or rules that govern printed language. Mechanics evolve over time as technologies empower new methods of composing.
Written language has some elements that distinguish it from oral speech. Writers use marks on a page to help readers sort words, numbers, clauses, phrases, and sentences in ways that facilitate comprehension.
Some elements of mechanics are really obvious, such as
- Run-on Sentences
- Sentence Fragments
- the use of italics and exclamation marks.
Some elements of language practice pertain to both written and oral discourse. This may explain why Grammar Handbooks and online websites (e.g., The Owl at Purdue University or Grammarly.Com or Wikipedia) disagree about whether or not some elements of discourse such as Modifiers, Parallelism (Parallel Structure), Punctuation or Sentence Fragments should be indexed under Grammar or Mechanics.
