### part of speech

adjective (conjectural)

### meaning for a pupil

(formal) Based on a guess or an idea that has not been proved, not on firm facts: «The date of the old map is conjectural». [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/C/conjectural/#m1)

### sense in the lessons

In history, science and maths texts, «conjectural» warns the reader that something is a guess: the colour of dinosaurs or the look of an ancient building may be conjectural. In maths, a conjecture is a statement that people think is true but nobody has proved yet (like the famous Goldbach conjecture). Phrases: «purely conjectural», «highly conjectural».

### note

Formal word. It comes from «conjecture» (a guess; to guess). Said «kun-JEK-cher-ul». In maths, «conjectural» means «not proved yet», which is different from «false»: a conjecture may turn out true or false. Similar words: speculative, hypothetical, unproven.
