You desire to pass on your knowledge to others and to learn from them as well. Teaching children or young adults may provide quite a lift for you. Games of strategy and skill challenge your intellect. You desire to communicate your thoughts in a clever, inspiring and dramatic manner. You may have acting, writing, or speaking ability.

Mercury in 7th House

If you have Mercury in the 7th House, your relationships tend to gravitate towards people who are intelligent, thought-provoking, witty and learned. You desire your spouse or business partner to be sharp, curious, clever and alert. You need to communicate and exchange ideas and information with your partner. Promotion of ideas to and from others appeals to you and you are always up for a good debate, discussion or argument.

You may spend much time thinking about your relationship or relationships in general. Marriage may be quite often on your mind. You desire a marriage or business partner that provides you with mental satisfaction and challenge. A partner who challenges you mentally and one who helps you function on more of an intellectual level is what you are looking for and need. Their value is enhanced if they help you better adapt and more effectively communicate with others. The person who gives you a lively flow of ideas, ideas that challenge and test your own mental processes, one who brings out your best mentally, stimulates you in a way that others may not understand. Yet that is what you seek in a partner. Your partner may be quick-witted, fluent, volatile, restless, high- strung as well as outspoken, argumentative, wordy and critical. Nervousness or mental imbalance may be present.

Your partner may possibly be connected with education, writing, traveling, sales, language interpretation or clerical, secretarial, typing or computer work.

In order to achieve the most positive results from any partnership you should learn to control your argumentativeness and your desire to criticize.
