   キムさんの電(でん)話(わ)番(ばん)号(ごう)を知(し)っていますか。

   Do you know Kim's telephone number?

   すみません、お名(な)前(まえ)は知(し)りません。

     我(われ)々(われ)は史(し)料(りょう)によって歴(れき)史(し)を知(し)る。

     Wareware wa shiryō ni yotte rekishi o shiru.

     We learn history through historic materials.

3. to be acquainted with, to know (someone)
4. (colloquial, in the negative) to care in the least about, to be concerned with,

   寿司(すし)ピザなんか知(し)らん。

   Sushi piza nanka shiran.

   I couldn't care less for sushi pizza.

When constructing this verb's affirmative present form, the ている construction is used, as in 知っている. However, as an irregularity, when forming its negative present form, the negative form of the ている construction is not, as would be expected, 知っていない, and instead becomes 知らない. Thus, extra care must be exercised when using this term.

This term is contrasted by 分かる, which is used for anything that involves conscious or continuous knowledge, while 知る is used for general facts. For example, the phrase

日(に)本(ほん)語(ご)を知(し)ります ― Nihongo o shirimasu ―  

would mean "I am acquainted with Japanese" or "I know what the Japanese language is". When saying "I know (have acquired) Japanese"

日(に)本(ほん)語(ご)が分(わ)かります ― Nihongo ga wakarimasu ―  

is used instead.
