Words that have extended their meanings
Over time, language changes and evolves. When the meaning of a word changes or evolves, and there is sufficient evidence to support this new meaning, it is the dictionary’s duty to record it. If you look in a dictionary at any entry with more than one definition, you are probably looking at a word which, through use over time, has developed meanings beyond its original sense.
Here is a list of some examples of words where the meaning has changed beyond the original sense. This list is by no means exhaustive.
noun 1. a program or list of things to be done, discussed, etc. 2. a list of matters to be brought before a committee, council, board, etc., as things to be done. 3. a set of motivating factors: he has an entirely different agenda to the others on the committee; there is a political agenda behind the recent grant to the farmers. –phrase 4. set the agenda, to decide what direction a group will take, as in politics, business, etc. [Latin, neuter plural of gerundive of agere do] Usage: The word is in origin a Latin plural, meaning `things to be done', but is regularly used as a singular in English (the agenda is quite short) and with the English plural -s (we can't have two agendas for one meeting).

(in the ancient Roman army) to select by lot and kill every tenth soldier of (a body of soldiers) as a punishment.4. Obsolete to take a tenth of or from. [Latin decimātus, past participle] Usage: Originally this word referred to the killing of one in ten, and by extension to the destruction of some part of the whole. It is now frequently used to refer to almost total destruction, but despite the weight of corpus evidence in favour of this shift in meaning, some writers still do not accept it.

Many writers avoid using the word in these senses because of the possibility of confusion and because they are becoming dated.
