W.O.W. - word of the week

Each week there will be at least one new Word of the Week or W.O.W. as well as a related question for online discussion.
Should you wish to reply to this question, please do so!
Recent WOWs are nearest to the top :)

Note:
I will not edit your grammar. I do however, suggest that you compose your responses in standard English NOT the text messaging language (or the lack thereof!) in which so many of you are so sadly proficient.

Professional
1. working in a profession
2. taking part in an activity such as sport or music, for money
3. very competent
4. person who works in a profession
5. person paid to take part in sport, music etc.

Volunteer
1. person who offers voluntarily to do something
2.to offer one's services regardless of skill
3. to give willingly

Tolerance
1. to allow or exist or happen
2. endure patiently
3. accept as inevitable the existence of other people's rights to their own opinions or actions
Q: Does this mean that if one is tolerant they are open-minded? Is our school tolerant?
