I'mAdam.Today'slessonisabitmoregrammar-based,orIguessyoucouldalsocallitvocabulary-based.

We'regoingtolookattheword"under",butwe'regoingtolookatitinaveryspecificcontext.

AndIhadalotofpeopleaskingmeaboutcertainwordsthatbeginwiththeword"under"andthentakeanotherwordwithit.

So,firstlet'smakesureweunderstandwhattheword"under"means.Firstofall,it'sapreposition,meaningithasafunctionintermsofmovementof

thingsorlocation,orpositioning.Anditmeans...whenwe'reusingitnowasaprefix...actually,Ishouldwritethis

A"prefix"isapartofawordthatcomesatthebeginningofaword,joinstoanotherwordandbecomesanewwordtogether.

So,asaprefix,"under"essentiallykeepsthesamemeaningasitdoesasapreposition.Itmeansless,orlower,ornotenough,orbeneath/belowwhichisthetraditionalmeaning

thatmostpeopleknow.So,herearesomewordswith"under"asaprefix,anditbasicallymeansexactlythe

samethingwiththeextraword.So,whatdoImean?

"Underachieve".Ifyouunderachieve,youachievelessthanyoucould;lessthanyourfullpotential.

So,anundergraduateisunderthat;lowerlevelofstudentwithinthesystem.Okay?

Soitbasicallymeanstheexactsamethingasthetwoparts;"under"and"graduate".Lowerthanagraduate.

Notenough:"Underdeveloped"meansithasn'tbeenfullydeveloped;it'snotdevelopedenough-verystraightforward.

Andbeneath/below:"Underground".So,thetrainis...thesubwayisunderground-meansit'sundertheground,andwejust

squeezethetwowordstogether;"under"becomesaprefix,"ground"becomes...staysthesameandyouhaveanewnoun.

Now,theproblemthatalotofpeoplehaveiswhenthetwowordsjointogetherandhaveacompletelydifferentmeaningoradifferentconnotation.

itdoesn'tmeanthatyou'reguessingloweroryou'reguessingless;itmeansyou'renotfullyappreciatingsomething.

So,ifyouunderestimateaperson'sstrengthorifyouunderestimateapieceofjewellery'svalue-meansyoudon'tthinkofitasmuchasitactuallyis.

So,it'slikeyoudidn'tguess...youdidtheguesscorrectly,that'strue;butyouguessedalowervalueforsomething,oralowerstrength,oralowersize,etc.

"Underlie"basicallymeansbethefoundation.So,technicallysomethingliesunder,butit'snothingphysical.

Soyouhavetobecarefulthattoknowit'sfoundationorbasisforsomething.To"undercut",again,youcouldcut,likeatree,youundercutatreemeansyou'recutting

itatalowerlevelandit'stoppingover-butamorecommonuseof"undercut",again,andespeciallyinbusiness,meanstoofferalowerpriceforsomething.
