     Some expressions in English can be really puzzling. Have a look at the following to see how it

challenges your brainpower.

Homeric laughter

     The "Homer" in this expression is the Greek poet. People laugh differently. Some laugh silently, while

others tend to laugh loudly. "Homeric laughter" refers to laughter of the latter kind. It is at times

uncontrollable, and the entire body shakes during the process. This kind of laughter is called Homeric

laughter because this is how the gods laughed in Homer's classics.

A three-ring circus

     When you refer to a situation as being a three-ring circus, you are saying that it is a situation of

complete confusion. There are so many activities taking place all together that they leave you confused or

annoyed. The expression comes from the world of entertainment - the circus. The area where the artists

perform their acts is called the "ring". In the past, some of the circuses were so grand that they had three

acts taking place simultaneously in three different "rings". The audience had to decide which "ring" they

wanted to focus on.

In the swim (of things)

     When someone is in the swim of things, the individual is actively participating in the things happening

around him, as in "I've been ill, but soon I'll be back in the swim of thing." In the world of fishing, fishermen use the word "swim" to refer to the section of the lake/river where fish can be found in plenty. So, if you

are a fisherman and wish to catch a lot offish, where would you be? You would be "in the swim".

Chickens have come home to roost

     The word "roost" refers to the place where birds rest. It could be anything - the branch of a tree, a

henhouse, etc. The expression is normally used to mean that the bad things that someone did in the past

have come back to bite or upset the individual. In other words, one has to face the consequences of the

deeds done in the past. The original form of this 700-year-old expression was "curses are like chickens;

they always come home to roost".
