You can't have your cake and eat it
You can't have your cake and eat it (too) is a popular English idiomatic proverb or figure of speech. The proverb literally means "you cannot simultaneously retain your cake and eat it". Once the cake is eaten, it is gone. It can be used to say that one cannot or should not have or want more than one deserves or is reasonable, or that one cannot or should not try to have two incompatible things. The proverb's meaning is similar to the phrases "you can't have it both ways" and "you can't have the best of both worlds."
Many people are confused by the meaning of "have" and "eat" in the order as used here, although still understand the proverb and its intent and use it in this form. Some people feel the above form of the proverb is incorrect and illogical and instead prefer: "You can't eat your cake and [then still] have it too", which is in fact closer to the original form of the proverb (see further explanations below) but uncommon today. Another variant uses "keep" instead of "have".
The phrase occurs with the clauses reversed in John Heywood's "A dialogue Conteinyng the Nomber in Effect of All the Prouerbes in the Englishe Tongue" from 1546, as "wolde you bothe eate your cake, and have your cake?". In John Davies' "Scourge of Folly" of 1611, the same order is used, as "A man cannot eat his cake and haue it stil." In Jonathan Swift's 1738 farce "Polite Conversation", the character Lady Answerall says "she cannot eat her cake and have her cake."
The order was reversed again in a posthumous adaptation of "Polite Conversation" in 1749, "Tittle Tattle; or, Taste A-la-Mode", as "And she cannot have her Cake and eat her Cake." From 1812 (R. C. Knopf's "Document Transcriptions of War of 1812" (1959) VI. 204) is a modern-sounding recording of "We cannot have our cake and eat it too."
Paul Brians, Professor of English at Washington State University, points out that perhaps a more logical or easier to understand version of this saying is, "You can’t eat your cake and have it too." Professor Brians writes that a common source of confusion about this idiom stems from the verb to have which in this case indicates that once eaten, keeping possession of the cake is no longer possible, seeing that it is in your stomach (and no longer exists as a cake).
Alternatively, the two verbs can be understood to represent a sequence of actions, so one can indeed "have" one's cake and then "eat" it. Consequently, the literal meaning of the reversed idiom doesn't match the metaphorical meaning. The phrase can also have specialized meaning in academic contexts; Classicist Katharina Volk of Columbia University has used the phrase to describe the development of poetic imagery in Latin didactic poetry, naming the principle behind the imagery's adoption and application the "have-one's-cake-and-eat-it-too principle".
In English, "have" can mean "eat", as in "Let's have breakfast" or "I'm having a sandwich". So the saying "You can't have your cake and eat it too" may mean that you can't eat the cake and then eat it again; or less metaphorically, that what you want is unreasonable. This interpretation makes sense in both the "have-eat" and "eat-have" iterations of the idiom, and might explain why the earliest known iteration is "have-eat".[original research?]
