Word choice refers to the poet's poetic diction. In Dover Beach', Matthew Arnold uses formal diction. He chose his words carefully. When he says that the world does not give us love', he means that the world lacks imagination and can know very little about time past, which is crystallized in ancient literature like a leaf in amber, knowledge of which is an essential precondition for love. He does not mean that love does not exist, but that it comes only from a partner who, unlike the world can share the exquisite perception and resolution such as he describes in Dover Beach'.
