10.PassageOne

Englishisoneofthemostimportantlanguagesoftheworldtodayspokenbymorethan300,000,000people,enditisthesecondwidelyusedmodemlanguage.OnlyChineseisspokenbymorepeople.

LinguistsclassifyEnglishasaGermaniclanguage.Itsclosestlinguistic"relatives"areFrisian,Dutch,Flemish,andLowGerman.MoredistantrelativesincludeSwedish,Danish,Norwegian,Icelandic,andModemHighGerman.Itsmostdistant"relatives"includeothermembersoftheIndo-EuropeanlanguagefamilyofwhichtheGermaniclanguagesareapart.

TheEnglishlanguageaswecurrentlyknowitistheresultofapproximately1500yearsofdevelopment.Interestingly,theoriginsofmodernEnglisharenotinEnglanditself,butinsouthernDenmarkandnorthernGermany,sincethelanguagewhicheventuallydevelopedintomodernEnglishwasbroughtbypeoplecalledtheAngles,Saxons,andJuteswhentheyinvadedtheBritishIslesinthefifthCentury.TheCelticlanguagespokenbytheearliestinhabitantsofEnglandweredisplacedandtheCeltic-speakingpeopleweredrivenbytheinvadersintowhatwenowknowasWales,Scotland,endIreland.Celticlanguagesarestillspokeninpartsofthesecountries.

LinguistsdividethedevelopmentofEnglishhim3periods;OldEnglish,MiddleEnglish,andModemEnglish.TheModemEnglishperiodisthenfurtherdividedintoEarlyModemEnglishendLateModemEnglish.TheOldEnglishperiodspannedapproximately500years--fromaround450toaround1100.TheMiddleperiodlastedroughly400years--fromabout1100untilaround1500.TheModemEnglishperiodbeganaround1500,withEarlyModemEnglishlastinguntilapproximately1750endLateModemEnglishfromthentothepresent

ThevocabularyofModernEnglishisprobablymoreextensivethenthatofmayotherlanguagesintheworld.IthasbeenestimatedthatthetotalnumberofModemEnglishwordsisover1,000,000,ifoneincludesslangendrecenttechnicalandscientificterms.

ThegreatnumberofwordsintheModemEnglishlexiconislargelyduetothefactthatEnglishhasbeenalwaysa"word-borrowing"language.IntheOldEnglishperiod,therewereborrowingsfromLatin,Greek,Danish,and,toasmallextent,Celticlanguages.IntheMiddleEnglishperiod,therewerefurtherborrowingsfromDanish,andalso—toalargedegree--fromNormanFrench.IntheModernEnglishperiod,therehavebeenmoreborrowingsfromLatin,Greek,andalargenumberofEuropeanandotherlanguages.Allinall,Englishhas"adopted"wordsfrommorethan50otherlanguages.
