If I Were a Boy is an Albanian novel written in a form derived from latin from a greek word meaning
Epistolary novel An epistolary novel is a novel written as a series of documents. The usual form is letters, although diary entries, newspaper clippings and other documents are sometimes used. Recently, electronic "documents" such as recordings and radio, blogs, and e-mails have also come into use. The word "epistolary" is derived from Latin from the Greek word ἐπιστολή "epistolē", meaning a letter (see epistle).
Plural form of words ending in -us In English, the plural form of words ending in "-us", especially those derived from Latin, often replaces "-us" with "-i". There are many exceptions, some because the word does not derive from Latin, and others due to custom ("e.g.", "campus", plural "campuses"). Conversely, some non-Latin words ending in "-us" and Latin words that did not have their Latin plurals with "-i" form their English plurals with "-i". Some words' plurals end in "-i" even though they are not Latin, or that is not the Latin plural, "e.g.", "octopi" as a plural for octopus. Prescriptivists consider these forms incorrect, but descriptivists may simply describe them as a natural evolution of language.
