Effective Writing is writing which has a logical flow of ideas and is cohesive to communicate. This means it holds together well because there are links between sentences and paragraphs. 

Principles of effective writing: 

• Clarity is a basic requirement for all writing. The basic purpose of writing is to clarify and inform. Therefore, the writing should be clear, orderly, readable, and in a language understandable to the audience. 
• The writer should produce a sense of form and right proportion, a sense of words that fit the ideas that he/she wants to convey. Therefore, the writing should be concise and short. 
• The sentences should be simple and should avoid complex sentences. 
• The writing should be free from any kind of error like grammar and ambiguity. There should be correctness in the writing. 

​Note: Stress on hyperboles and Liberal use of adjectives are part of writing but using these won't make the writing effective. The use of complex sentences may lead to ambiguity in the writing.

Hence, The principles of effective writing useful for both students and teachers are Clarity, Conciseness, and Correctness.
