““Ecthelion must be similarly from Aegthelion. Latter element is a derivative of √stel 'remain firm'. The form with prefix ' sundóma ' , estel , was used in Q{uenya} and S{indarin} for 'hope' – sc. a temper of mind, steady, fixed in purpose, and difficult to dissuade and unlikely to fall into despair or abandon its purpose. The unprefixed stel- gave [? S verb] thel 'intend, mean, purpose, resolve, will'. So Q ? þelma 'a fixed idea,..., will.””
