the meaning of "laile"
My book mentions the phrase "lai le" as meaning "here you are" when you hand something over (in their example it is food as in kafei lai le". My dictionary has the character "lai" as 2nd tone and meaning to come but it doesn't have the "le" character. Is "le" pronounced fifth tone?

My book mentions the phrase "lai le" as meaning "here you are" when you hand something over (in their example it is food as in kafei lai le". My dictionary has the character "lai" as 2nd tone and meaning to come but it doesn't have the "le" character.  Is "le" pronounced fifth tone?

Answer

Here le without tone. or as you put it the fifth tone.
lai le means Somebody is coming!
E.g. 
Mom:the dinner is ready! Son:laile!(means I'm coming!!!)
le is a postfix here! Just a fixed pattern.Aother example:

hao le!好了！hao(3rd tone) means good!But haole means It's ready.It's finished.
E.g. Mom: Fan(4) hao(3) le 饭（Rice）is ready! Means the dinner is ready!

tai(4) hao le! Means Great!!!
E.G Teacher: We're going to the park tomorrow!!!
       Students:Tai hao le!(Great!!!!)
