Every \Ev"er*y\, a. & a. pron. [OE. everich, everilk; AS. [=ae]fre ever + [ae]lc each. See Ever, each.] 1. All the parts which compose a whole collection or aggregate number, considered in their individuality, all taken separately one by one, out of an indefinite number. [1913 Webster] Every man at his best state is altogether vanity. --Ps. xxxix. 5. [1913 Webster] Every door and window was adorned with wreaths of flowers. --Macaulay. [1913 Webster] 2. Every one. Cf. Each. [Obs.] "Every of your wishes." --Shak. [1913 Webster] Daily occasions given to every of us. --Hooker. [1913 Webster] Every each, every one. [Obs.] "Every each of them hath some vices." --Burton.. Every now and then, at short intervals; occasionally; repeatedly; frequently. [Colloq.] [1913 Webster] Note: Every may, by way of emphasis, precede the article the with a superlative adjective; as, every, the least variation. --Locke. Syn: Every, Each, Any. Usage: Any denotes one, or some, taken indifferently from the individuals which compose a class. Every differs from each in giving less prominence to the selection of the individual. Each relates to two or more individuals of a class. It refers definitely to every one of them, denoting that they are considered separately, one by one, all being included; as, each soldier was receiving a dollar per day. Every relates to more than two and brings into greater prominence the notion that not one of all considered is excepted; as, every soldier was on service, except the cavalry, that is, all the soldiers, etc. [1913 Webster] In each division there were four pentecosties, in every pentecosty four enomoties, and of each enomoty there fought in the front rank four [soldiers]. --Jowett (Thucyd. ). [1913 Webster] If society is to be kept together and the children of Adam to be saved from setting up each for himself with every one else his foe. --J. H. Newman.
