logical consistency and clarity
The quality of speech, writing, or ideas being clear and all fitting together in a logical way.
الگوی کاربرد:
the coherence of [an argument/writing/plan]
اشتباه رایج:
Learners often confuse 'coherence' with 'cohesion' in writing. 'Coherence' is about the logical flow of ideas, while 'cohesion' is about the links between sentences and paragraphs (for example, using words like 'however', 'therefore'). Another mistake is using 'coherence' as an adjective; the correct adjective is 'coherent'.
هممعنیها
consistency (Very close in meaning; often used for ideas following the same logic or rules, not just clear structure in communication.)
|
clarity (Focuses more on being easy to understand, while 'coherence' focuses on parts fitting together logically.)
متضادها
incoherence (Direct opposite; describes speech, writing, or thought that does not connect in a clear or logical way.)
|
confusion (Emphasizes the result of poor coherence in ideas or communication.)

quality of forming a unified whole
The quality of many parts working well together as one whole thing.
الگوی کاربرد:
the coherence of [a group/system/policy]
اشتباه رایج:
Learners may overuse this sense when they only mean simple 'unity' or 'teamwork'. Use 'coherence' when you want to stress that the parts fit together in a structured and stable way, not just that people are friendly or agree.
هممعنیها
unity (Stresses being together as one, especially in groups of people; 'coherence' focuses more on how well the parts fit and work together.)
|
integration (Focuses on parts being combined into a whole; 'coherence' also implies that the whole makes sense and is stable.)
متضادها
fragmentation (Describes something breaking into separate parts so that it no longer works as a whole, the opposite of coherence.)
|
disunity (Emphasizes that people or parts are not together or aligned, which breaks coherence.)

wave property: fixed phase relation
In physics, a quality of waves like light or sound, when they stay in step with each other so they can mix in a clear pattern.
الگوی کاربرد:
the coherence of [a light source/waves]
اشتباه رایج:
Learners sometimes mix the everyday sense of 'coherence' with the physics meaning. In scientific texts about waves, 'coherence' almost always refers to the phase relationship of waves, not to clarity or logical order.
هممعنیها
correlation (In this context, refers to a statistical or physical relationship between waves; 'coherence' is a more specific technical term about phase.)
متضادها
incoherence (In wave physics, describes waves that do not maintain a fixed phase relation, so they do not interfere in a stable way.)
