Hyperforeignisms can manifest in a number of ways, including the application of the spelling or pronunciation rules of one language to a word borrowed from another, an incorrect application of a language's pronunciation, and pronouncing anglicized words as though they were borrowed more recently. Hyperforeignisms may similarly occur when a word is thought to be a loanword from a particular language when it is not.
Although similar, words that exhibit deliberate language-play (such as pronouncing Report with a silent ⟨t⟩ in The Colbert Report or ironically pronouncing Target as // tar-ZHAY, as though it were an upscale boutique) are not, strictly speaking, hyperforeignisms. These are, instead, a way of poking fun at those who earnestly adopt foreign-sounding pronunciations of pseudo-loanwords.
Similarly, speakers who echo hyperforeign pronunciations without the intention of approximating a foreign-language pattern are also not practicing hyperforeignization; thus, pronouncing habanero as if it were spelled habañero is not a hyperforeignism if one is not aware that the word has been borrowed from Spanish.
