What's a Prefix ? (2)

2013/07/02

The prefix "pre" means "before".  So when it's added to the word "paid", for example,  it means "paid before" or "in advance".

An opposite meaning is given by the prefix "post".  This prefix means "after".  So when added to a word like "war", it means "after the war".  (ex: Japan's postwar economy grew quickly.)

A prefix like "dis" can have several meanings: "A loss of" or "Not do, for example.  The word "dishonor" means a lack or loss of honor.  On the other hand, "disconnect" means to "not to connect" or take away a connection.

A very common prefix is "Re".  It means, roughly, to do again.  So we "Rechange" or "change again" our mobile phones.

The prefix "pro" and "anti" have opposite meanings: "pro" is to be "for"(something) and "anti" is to be against it. (ex: "There were some anti-Japanese demonstrations in Beijing.")

"Ex" has the meaning of "previous, before" as in "ex-prime Minister Koizumi".

"Mis" usually has a meaning of "wrong" or "bad".  So we have "mis-understanding" (a wrong understanding of something.)

The prefix "ir" contains a meaning of "not".  Therefore, we have words like "irregular" (not regular) and "irresponsible" (not responsible).

Finally, the prefix "hyper" means "above" or "beyond" usual.  It makes words such as "hyperactive" (active more than usual) and the economic word "hyperinflation". (inflation much beyond the normal level).                    (G.K)
