"The double, and the triple."

[Stergi3]

Greek has got a kind of sound harmony in many cases. To avoid cacophony, called χασμωδία in Greek some words tranform as in case of και and κι here, some words are cut using apostroph in front or after the word.

Example: Θιός σχωρέστον, is used for a person who died. Θεός--->Θιός (God) συγχώρεσέ τον-->σ'χώρεσ' τον-->σχωρέστον

or
"ξέρω 'γώ;" instead of "ξέρω εγώ;" , colloquial, "ξερωγώ;"= I am not sure, I don't know, literally, do I know?.

Expressions used in every life, very frequently.

Γιατί όχι και "Το διπλό και το τριπλό"

Thanks for your feedback! This has been corrected! Enjoy the course!

[carmina_banana]

I agree with you. To me, it does not make to many sense as masculine and femenine...

What's the rule of grammar for: "κι η" vs. "και η"?

[fotiosgaridis]

It is wrong to write ...κι η τριπλή and a cacophony when you talk. Κι is mainly used to replace και when the next word starts with ε:

Example

• Εσύ κι εγώ, εγώ κι εσύ

BUT

• Ο πατέρας και η μητέρα. (You shouldn't write ο πατέρας κι η μητέρα)

Both κι and και can be used when the next word starts with any vowel:

• Ελεύθερος [κι / και] ωραίος

• Γλυκό [κι / και] αλμυρό

• Γη [κι / και] ουρανό

In all the latter examples it is more frequent the use of κι in the spoken language as it is shorter and faster to pronounce.

[Gitirana]

"Ο διπλός, κι η τριπλή."??? It is written "κι" instead of "kai".

[Dimitra956826]

If you check the comment right above, you can see that κι is a form of και, used before vowels. Both are accepted in this case, since κι can be used (since it is indeed followed by a vowel, η) but it does sound a bit odd (personally I don't think it's a cacophony, more like just something odd), and και is not incorrect. So, use whichever one you like. ^.^

I had never seen that before in the lessons, if I can remember.
Thanks for your attention! :)
