Uh there is no word for woman deacon because deacon is without any specific gender. Paul actually creates a word in the 1 Timothy 3:11 to address women. There has been and continues to be much discussion concerning how that verse should be translated some say wife (which is loosing favor among scholars) and others say woman or even woman deacon. Though I am not a huge John MacArthur fan, he does a good job discussing this passage in his commentary and comes to the conclusion that Paul here was addressing men deacons and women deacons, two different "offices" or "roles" in the church.
