When yu pen a dictinary, yu ften cme acrss a lt f unfamiliar wrds. Yu might think this is a bit scary. But many f them are frmed using ther simpler wrds. This is called wrd frmatin. Wrds frmed by cmbining ther wrds are called cmpunds, fr example, __________ (a friend that yu cntact by writing, traditinally using a pen) and __________ (knwn by many peple).
Prefixes and suffixes ften have fixed meanings. If yu add un- r in- t a wrd, the new wrd usually means the ppsite. Fr example, if smething isn’t crrect it’s ________, and if smene isn’t happy they are _________. Wrds with the suffixes -ment and -ness are ften nuns. Fr example, if smebdy has imprved a lt, they have made great ____________.
Sme nuns and adjectives can be used as verbs, r the ther way rund. When we calm smebdy dwn, they becme ______. And we can give smene a present by__________ it. And smetimes a wrd is made up f the first letters f several wrds: “Wrld Trade Organizatin ” can be referred t as _____ , and ______is shrt fr “as sn as pssible”. It is impssible t knw the meaning f every wrd, but knwing abut wrd frmatin can help us guess their meanings.

Sme American spellings were created by Nah Webster, wh made ne f America’s first dictinaries. He changed “ -re” spellings t“ -er ”, which is why________ is spelt _______ in American English. The Americans and the British als use different wrds fr everyday things. Fr example, Americans talk abut putting ______ in their cars and driving alng the ___________, whereas in the UK, peple put _________ in their cars and drive alng the ___________. Americans take the_________ t the tp flr f a building, but the British use the _____. In the US, they take the _________, but in the UK, peple travel n the _____________, Americans live in a(n) ___________ while the British live in a(n) _______. It’s nt as cnfusing as it seems: usually peple frm the tw cuntries can understand each ther frm the cntext. But that desn’t stp them having a friendly argument abut which wrd is the “right” ne!
