Why is precision of language so important in The Giver?

In the Giver, controlling language was controlling thought, and for preventing emotions seen as dangerous. Using the word love, could lead people to consider familial relations more important then the state, and people were only allowed to express state sanctioned emotion. This piggy backs off of Orwell's idea of dystopian regimes limiting language, and reducing simplifying the amount spoken to prevent people from having the ability to resist. Having medicines to control brain chemistry and keep people pliable and mostly emotionless goes one step farther then Orwellian control, in mopping up what ever propaganda couldn't wipe away. If people only use a certain vocabulary, to express certain ideas, other ideas can be dismissed as poor grammar, marginalizing the true problems of a society and sweeping them under the carpet.

Precision of language is important because it is meant to illustrate feelings and emotions. This is rather ironic because emotions are considered to be meaningless.
