Častá chyba:
Learners sometimes use "conjecture" when a simple, neutral word like "idea" or "plan" is meant. "Conjecture" always implies a lack of complete evidence. Also, some learners try to use it as a verb in patterns like *"make conjecture"* without an article; in most cases, say "make a conjecture" or use the verb "conjecture" instead.

Synonyma
speculation (Very close in meaning; common in both everyday and academic contexts, slightly less formal-sounding than "conjecture".)
|
guess (More informal and everyday; does not suggest careful thought in the way "conjecture" often does.)
|
surmise (Somewhat formal and literary; often suggests a quick or intuitive conjecture.)
Antonyma
fact (A piece of information that is known to be true, not just suspected.)
|
certainty (A state of being completely sure, the opposite of a tentative guess.)
|
proof (Clear evidence that shows something is true, rather than a view based on limited information.)

Častá chyba:
Learners sometimes say *"conjecture about that"* when a clause is needed: in formal writing, prefer "conjecture that..." with a full sentence after it. Also, avoid *"conjecture of"* for this verbal meaning; use "conjecture that" or simply a noun phrase, e.g. "conjecture about the cause" (noun).

Častá chyba:
Learners sometimes confuse "conjecture" with "theorem" in mathematics. A conjecture is not yet proved; a theorem has already been proved. Also, outside mathematics, "conjecture" is more general, but this technical sense is specifically about mathematical statements.

Synonyma
hypothesis (In mathematics and science, a tentative statement; in pure math, "conjecture" more strongly suggests something widely believed but unproven.)
|
unproven theorem (Informal description within mathematics; once proven, it becomes a true theorem, not a conjecture.)
Antonyma
theorem (A mathematical statement that has been proven, opposite to an unproven conjecture.)
