"Hydrophobia" joke

One day a Sinhala teacher explained the meaning of Hydrophobia to
his class in the following way:

"Now students what you do when you see a big word in Sinhalese?
You break it up into small small words and try to get the meaning
of it.
For example let's take Hydrophobia and break it up into small
small words:

High-dorrh-four-bee-yahh....
High kiyanne uda
Dorrh kiyanne dora
Four kiyanne hathara
Bee kiyanne mee-massa
Yahh kiyanne mee masi-nahdaya
Ethakota lamaiyne Mee masso hathra denek dora uda indagena nadha
karanakota Hydrophobia....
