The word 'appointment' can have two main meanings in the common use of the language that have little to do with each other. However, both are common and are usually used normally.
The main idea of a quote is one that indicates the repetition of an idea, phrase or construction of language previously made by another person. Here we speak then of quotation as an expression of human language that allows us to connect ideas with previous authors and thus give greater richness or justification to what one tries to establish. The use of citations in the intellectual field supposes an important system of naming of the one who created the phrase previously in order to avoid confusion. The appointment must therefore be made mentioning the author, the work from which the phrase was withdrawn and other elements such as page, chapter and others. Typically, citations from another author may vary in length, although short to medium lengths are especially recommended.
The second common meaning of the word appointment, which does not have much to do with the previous one, is that which indicates the meeting of two or more people in a specific space and time, previously arranged by mutual agreement. When we talk about dating in this sense, we are referring to different types of encounters that can be of a work, love, informal or formal type, of long or short duration, with different objectives, depending on each particular situation. Normally, each of these types of appointment has a particular number of elements such as language, clothing, corresponding spaces and other accessories such as duration, activity to be carried out or others. It is important to note that, whatever the case, appointments understood as meetings always assume that the meeting space and place is decided by mutual agreement so that the parties to meet can effectively attend.
