    Usage notes
    * The verb is construed in a few different ways: ** With a direct object, as in “I need your help.” ** With a to -infinitive, as in “I need to go.” Here, the subject of serves implicitly as the subject of the infinitive. ** With a clause of the form “for [object] to [verb phrase]”, or simply “[object] to [verb phrase]” as in “I need for this to happen” or “I need this to happen.” In both variants, the object serves as the subject of the infinitive. ** As a modal verb, with a bare infinitive; in negative polarity contexts, such as questions (“Need I say more?”), with negative expressions such as not (“It need not happen today”; “No one need ever know”), and with similar constructions (“There need only be a few”; “it need be signed only by the president”; “I need hardly explain the error”). . ** With a gerund-participle, as in “The car needs washing”, or (in certain dialects) with a past participle, as in “The car needs washed”[http://itre.cis.upenn.edu/~myl/languagelog/archives/003106.html] (both meaning roughly “The car needs to be washed”). ** With a direct object and a predicative complement, as in “We need everyone here on time” (meaning roughly “We need everyone to be here on time”) or “I need it gone” (meaning roughly “I need it to be gone”). ** In certain dialects, and colloquially in certain others, with an unmarked reflexive pronoun, as in “I need me a car.” * A sentence such as “I need you to sit down” or “you need to sit down” is more polite than the bare command “sit down”, but less polite than “please sit down”. It is considered somewhat condescending and infantilizing, hence dubbed by some “the kindergarten imperative”, but is quite common in American usage.You Need To Read This: How need to vanquished have to, must, and should.” by Ben Yagoda, Slate, July 17, 2006
