Branches are spawned from trunk (or other branch) in order to concentrate on stabilizing the tree for release or to start implementing long-term (possibly throw away) changes that would disturb development in trunk. CVS and other version control systems use the word HEAD instead of trunk. The trunk refers to the unnamed branch - version of a file tree under revision control.
