1
logical, clear, and easy to follow
Clear and logical, so other people can easily understand what is said or written.
الگوی کاربرد:
a coherent [argument/explanation/account/text]
اشتباه رایج:
Learners sometimes confuse "coherent" with "cohesive." "Coherent" focuses on clear, logical meaning (an argument, explanation, or story that makes sense), while "cohesive" focuses on how well parts are linked together (for example, sentences joined with good linking words). Another mistake is saying *"a coherence argument"* instead of *"a coherent argument"*; remember that "coherent" is the adjective, "coherence" is the noun.

|

2
able to think and speak clearly
Able to think and speak clearly and in an organized way.
الگوی کاربرد:
[someone] is/was/seems coherent
اشتباه رایج:
Learners sometimes use "coherent" for people when they really mean "cooperative" or "polite." "Coherent" here is only about mental clarity and clear speech, not about being kind or helpful.
هممعنیها
lucid (Common in medical or care contexts for someone whose mind is clear and who can communicate well.)
|
clear-headed (Informal; emphasizes practical, calm thinking rather than just understandable speech.)
متضادها
incoherent (Describes a person whose speech or thoughts are disorganized and hard to understand, often due to illness, shock, or intoxication.)
|

3
consistent and forming a unified whole
Made of parts that all fit together well and do not conflict, so the whole thing works or makes sense.
الگوی کاربرد:
a coherent [plan/strategy/policy/system/set]
اشتباه رایج:
Learners sometimes use "coherent" when they really want "united" or "together" for people (e.g. *"a coherent team"*). While possible, it usually sounds more natural to say the team has a "coherent strategy" or a "coherent way of working" rather than that the people themselves are coherent.
هممعنیها
consistent (Focuses on the idea that parts do not contradict each other; may not always imply good structure or design.)
|
integrated (Highlights that different parts are combined and work together smoothly as a system.)
|
unified (Emphasizes that the whole acts as one unit, without division or conflict.)
متضادها
fragmented (Describes something broken into pieces that do not fit together well as a whole.)
|
patchy (Informal; describes something made of weak, incomplete, or badly matched parts.)
|
inconsistent (Describes a plan or set of ideas whose parts do not agree with each other.)
