Iterator it = map.entrySet().iterator();
while (it.hasNext())
{
Entry item = it.next();
map.remove(item.getKey());

Testing for admissible sequences

What is an "admissible" sequence?

Expletive infixation is a process by which an expletive or profanity is inserted into a word, usually for intensification. It is similar to tmesis, but not all instances are covered by the usual definition of tmesis because the words are not necessarily compounds.
