A medium is a person who is psychic and also has the ability to communicate with spirits, (but not all psychic's are mediums.)
Mediums may also be described as 'channels' or 'channellers.'
The word medium means:
a means or instrument for storing or communicating information
an intervening substance through which signals can travel as a means for communication
someone who serves as an intermediary between the living and the dead.
There are many more meanings for the word medium but the above three highlight why this word was chosen for a medium.
A medium 'picks up' information from the spirit world by several means, some will use only one of the following, but many use a combination of the following:
Clairvoyance: literally means 'clear seeing' and refers to mediums who see spirits, they may see them in solid form or see them psychically, they may recieve messages as symbols which they then need to interpret and pass on to their client.
Clairaudience: this literally means clear hearing and refers to mediums who hear spirits, they may hear the voices of the actual spirit, or hear them in their own voice, often this 'hearing' is heard in thought form, yet others hear very clearly and directly in their ear.
Clairsentience: This is probably the commonest of the the three and means clear sensing or feeling, this is when the medium picks up on a spirit's feelings or 'senses' spirits.
