It is to incorporate Greek into English sentences.
Consider these sentences:
- I'm going to eat some vegetables and κρέας for dinner.
- Κρέας is the σάρξ of animals.
- We go to a μάκελλον to buy κρέας.
- The μάκελλον is one stand or one part of the larger ἀγορά.
- If you are thirsty, you can buy a πόμα to drink.
- People sell many types of πόματα at the ἀγορά.
- The most basic πόμα for human beings is ὕδωρ.
- ὕδωρ from the sky is βροχή.
- ὕδωρ that flows from the mountains to the sea is a called a ποταμός.
- While we speak of one ποταμός, we speak of many ποταμοί.
- The little fast flowing ποταμοί that that start in the mountains are called ῥεύματα.
- While we speak of many ῥεύματα, we speak of one ῥεῦμα.
- If you want to drink ὕδωρ from a ποταμός it is best to ζεῖν it first.
- To ζεῖν the ὕδωρ, you will need to kindle a πῦρ.
- A πῦρ needs something to καεῖν.
- The best thing to καεῖν is ὕλη.
- ὕλη is what a δένδρον is made of.
- So to get ὕλη we could κόπτειν a κλάδος from a δένδρον, but that type of ὕλη is not good to καεῖν because it is not ξηρά.
- ξηρὰ ὕλη will produce very little κάπνος.
- If smoke gets into our ὀφθαλμοί, then we can't see.
- But be careful here, because ὀφθαλμοί is the word we use when we are seeing, but if we talk about the physical organs of our body, we call them ὄμματα.
- For most people, their δεξιὸς ὀφθαλμός is dominant and their ἀριστερός one is weaker.
- But if you are a ἀριστερόχειρ person, then you ἀριστερὸς ὀφθαλμός will probably be dominant.
- A lot of δένδρα together is also called an ὕλη, because we don't really see individual δένδρα, but we know that we can get a lot of ὕλη from it.
- We can ζεῖν the κρέας that we want to eat in ὕδωρ.
- If we want to cook it over the πῦρ and not use ὕδωρ to transfer the θερμότης to the food for cooking, that is not ζεῖν, but ὀπτᾶν.
