Dadamac definitions are going to help me solve a problem with words.
Words are "slippery" things - hard to get a firm hold on for any length of time. They have different meanings in different contexts. Some have regional variations - check out the Cornish use of the words "maid" and "lover". Meanings change over time - what about "gay", "cool" and "wicked"?
By writing a dadamac definition I'm giving myself permission to make a word mean what I say it means (while recognising that other people may have other ideas).
