The importance of communication is the bedrock of The Five Love Languages. In any healthy relationship, communication is key; it must be maintained for healthy and loving interactions. The love languages outlined in the text are different forms of communication—even physical touch and acts of service function as means by which we communicate our feelings, our love, for our partners.

Our emotional tank stores the feelings and memories of when others have expressed their love for us. In order to run at maximum efficiency, our emotional tank needs to be filled. When it feels empty, it is because we have experienced a lack of loving communication from our partner. Learning to speak the love languages will ensure that we can keep the emotional tank of our loved ones filled to the brim.

The ecstatic, out-of-body experience that characterizes the initial sparks of romantic attachment are known as euphoria (a Greek word that literally means “to carry something well,” “to be healthy,” or “to exist in a desirable way.”) The feeling of romantic euphoria is a universal experience. However, it is ephemeral. In the majority of instances it fades and returns only in spurts. Mature and intentional love carries a relationship past the state of euphoria into the state of true and lasting love.
