everywhere,.everyplace.adverb
in any or every place; in all places. See Usage Note at  everyplace.
Usage note:.the forms everyplace (or every place), anyplace (or any place), someplace (or some place) and no place are widely used in speech and informal writing as equivalents for everywhere, anywhere, somewhere and nowhere. Though these usages are not incorrect, they should be avoided in formal writing. But when the two-word expressions every place, any place, some place and no place are used to mean 'every', 'any', 'some' or 'no' spot or location, they are entirely appropriate at all levels of style. The distinction between the two meanings is often subtle, but acceptability can often be gauged by seeing whether an expression with 'where' can be substituted. Thus in the sentence 'She has taken extensive photographs of every place she's ever lived in', substitution of the word 'everywhere' would make no sense and one can conclude that the sentence would be inappropriate in formal writing. See more Usage notes

Usage note: Every is representative of a large class of English words and expressions that are singular in form but felt to be plural in sense. The class includes, for example, noun phrases introduced by 'every' and 'any'. These expressions invariably take a singular verb; we say 'Every car has (not 'have') been tested'. We say 'Anyone is (not 'are') liable to fall for a con job' .
   But when a sentence contains a pronoun whose antecedent is introduced by 'every', grammar and sense pull in different directions. The grammar of these expressions requires a singular pronoun, as in 'Every car must have its brakes tested', but people persist in using the plural pronoun as in 'Every car must have their brakes tested'. Although the latter pattern is common in the speech of all groups, it is still widely regarded as grammatically incorrect in writing.
   The effort to adhere to the grammatical rule leads to various complications, however. The first is grammatical. When a pronoun refers to a phrase containing 'every' or 'any' that falls within a different independent clause, the pronoun cannot be singular. Thus it is simply not English to say 'Every man left; he took his raincoat with him'. Nor can one say 'No one could be seen, could he?' Writers unwilling to use plural forms in these examples must find another way of expressing their meaning, either by rephrasing the sentence so as to get the pronoun into the same clause (as in 'Every man left, taking his raincoat with him') or by substituting another word for 'every' or 'any' (as in 'All the men left; they took their raincoats with them').
   The second complication is political. When a phrase introduced by 'every' or 'any' refers to a group containing both men and women, what shall be the gender of the singular pronoun? This matter is discussed in the Usage note at he. See more Usage notes.
