One thing about learning Greek is getting over the fact that they miss out vowels where a regular civilised person would expect a vowel to be.

Look at this sign for a vet. The Greek word for vet Kτηνaτρεio starts with a K and a T, which are letters that sound the same in English.
If the British were inventing a word like this we would force ourselves to insert at least a little "i" as a proper division between two hard vowels.

But not this mob.

They just batter right on. K-Teen-ee-ah-tree-oh.

Nutty as a fruit cake. But you get used to it.
