In a thoughtful, careful, and deliberate manner that respects others' feelings.
From 'considerate' (thoughtful, respectful) + the adverbial suffix '-ly'. 'Considerate' derives from Latin 'considerare' (to observe carefully), from 'com-' (with) + 'siderare' (to observe).
The root 'siderare' actually means 'to observe the stars'—so to be considerate literally means to look at something carefully 'like a star-gazer,' bringing deep attention to what matters.
