Morphology
unchartered = chartered (transparent) = un + charter + ed
The negative prefix 'un-' attached to 'chartered' straightforwardly yields 'not chartered', which learners can infer from knowing 'chartered' and the productive prefix 'un-'.
Etymology
Unchartered breaks into un- 'not' and charter, a word for a written 'paper' that gives official permission or rights, so it helps to imagine a missing document. So unchartered means lacking that official paper and not formally allowed or established.
