Morphology

proposition = propose (semi-transparent) = pro + posit + ion

The logical sense 'a statement that is true or false' is historically and semantically related to 'that which is put forward', but the technical/logical meaning is specialized and may not be inferable from everyday 'propose'.

Etymology

Proposition in logic is a statement 'put forward' for people to decide if it is true or false; the word comes from Latin pro- 'before' and ponere 'to put', so a logical proposition is an idea someone places before others to be judged.
