to enable
'ermöglichen' and 'gewährleisten' both have to do with something being able to happen or work well. 'ermöglichen' means: you create the conditions so that something becomes possible. Whether it actually happens is not always the main focus. 'gewährleisten' is stronger: you make sure or guarantee that something works reliably or has a certain quality. Learners may confuse the words because both often appear with plans, technology, or organization. As a guide: 'ermöglichen' fits when an opportunity or possibility is created; 'gewährleisten' fits when safety, certainty, or reliability is emphasized.
