logical consistency and clarity
The quality of speech, writing, or ideas being clear and all fitting together in a logical way.
用法パターン：
the coherence of [an argument/writing/plan]
よくある間違い：
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'.
類義語
consistency (Very close in meaning; often used for ideas following the same logic or rules, not just clear structure in communication.)

対義語

quality of forming a unified whole
The quality of many parts working well together as one whole thing.
用法パターン：
the coherence of [a group/system/policy]
よくある間違い：
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.
類義語
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.)
対義語
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.
用法パターン：
the coherence of [a light source/waves]
よくある間違い：
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.
類義語
correlation (In this context, refers to a statistical or physical relationship between waves; 'coherence' is a more specific technical term about phase.)
対義語
incoherence (In wave physics, describes waves that do not maintain a fixed phase relation, so they do not interfere in a stable way.)
