Those of you who remember The Boomtown Rats should be able to work out the title! This topic is describing how to express your likes and dislikes in Greek. To make things complicated Greek doesn't seem to have a verb "to like" but rather they use a verb which would be more literally translated as "to be liked" so instead of saying "I like it" you have to turn the phrase around and say "By me, it is liked". Of course the Greek condenses all those words into just one and a bit words:
By me becomes just Μ' which is short for ΜΟΥ, and
it is liked becomes just αρέσει/ΑΡΕΣΕΙ (3rd person singular of the verb αρέσω/ΑΡΕΣΩ)
Similarly if it's "you" doing the liking then ΣΟΥ is shortened to just Σ' (unless it's plural or formal in which case ΣΑΣ remains in full)
So together this looks like:
 

English	Lower	Upper
I like ...[he/she/it]	μ'[ου] αρέσει...	Μ'[ΟΥ] ΑΡΕΣΕΙ
I like …[them]	μ'[ου] αρέσουν...	Μ'[ΟΥ] ΑΡΕΣΟΥΝ
[Do] you like …[he/she/it]?	σ'[ου] αρέσει ...;	Σ'[ΟΥ] ΑΡΕΣΕΙ;
[Do] you like …[them]?	σ'[ου] αρέσουν ...;	Σ'[ΟΥ] ΑΡΕΣΟΥΝ;
and by deduction:
I like you	μ'[ου] αρέσεις	Μ'[ΟΥ] ΑΡΕΣΕΙΣ
[Do] you like me?	σ'[ου] αρέσω;	Σ'[ΟΥ] ΑΡΕΣΩ;

And to go with these phrases you can use use "δεν/ΔΕΝ" in front to say you don't like something or at the end you can add "πολύ/ΠΟΛΥ" or "πάρα πολύ/ΠΑΡΑ ΠΟΛΥ" at the end to say you like it "a lot" or "very much".
Of course when asked if you like something you can just reply "ναι" or "οχι" - you don't have to repeat the whole "μ'αρέσει".
Remember in Greek that the articles get used all the time (where we would drop the article - "I like wine" as it means something slightly different to "I like the wine") so here are a few examples:
 

English	Lower	Upper
I like wine	μ' αρέσει το κρασί	Μ' ΑΡΕΣΕΙ ΤΟ ΚΡΑΣΙ
I like wines	μ' αρέσουν τα κράσια	Μ' ΑΡΕΣΟΥΝ ΤΑ ΚΡΑΣΙΑ
Do you like red cars?	σ' αρέσουν τα κόκκινα αυτοκίνητα;	Σ' ΑΡΕΣΟΥΝ ΤΑ ΚΟΚΚΙΝΑ ΑΥΤΟΚΙΝΗΤΑ;
Do you like Greece?	σ' αρέσει η Ελλαδα	Σ' ΑΡΕΣΕΙ Η ΕΛΛΑΔΑ
I don't like green olives	δεν μ' αρέσουν οι πρασινες ελλιες	ΔΕΝ Μ' ΑΡΕΣΟΥΝ ΟΙ ΠΡΑΣΙΝΕΣ ΕΛΛΙΕΣ
I like coffee very much	μ' αρέσει ο κεφες πάρα πολύ	Μ' ΑΡΕΣΕΙ Ο ΚΕΦΕΣ ΠΑΡΑ ΠΟΛΥ
I like tea a little	μ' αρέσει το τσαι λίγο	Μ' ΑΡΕΣΕΙ ΤΟ ΤΣΑΙ ΛΙΓΟ
Don't you like beers much?	δεν σ'αρέσουν οι μπίρες πολύ;	ΔΕΝ Σ'ΑΡΕΣΟΥΝ ΟΙ ΜΠΙΡΕΣ ΠΟΛΥ;

Another word worth mentioning on this topic is the verb προτιμώ/ΠΡΟΤΙΜΩ meaning "I prefer" which allows a few distinctions to be made - "Do you like white wine?"/"I prefer red" - "Σ'αρέσει το λευκο κρασί;"/"Προτιμώ κόκκινο" ("Σ'ΑΡΕΣΕΙ ΤΟ ΛΕΥΚΟ ΚΡΑΣΙ;"/"ΠΡΟΤΙΜΩ ΚΟΚΚΙΝΟ" for the capital hungry of you).
To finish, for comepleteness here is how anyone and everyone likes things:
 

English	Lower	Upper
I like it	μ'[ου] αρέσει	Μ'[ΟΥ] ΑΡΕΣΕΙ
You like it	σ'[ου] αρέσει	Σ'[ΟΥ] ΑΡΕΣΕΙ
He/it likes it	του αρέσει	ΤΟΥ ΑΡΕΣΕΙ
She likes it	της αρέσει	ΤΗΣ ΑΡΕΣΕΙ
we like it	μας αρέσει	ΜΑΣ ΑΡΕΣΕΙ
You like it (pl. or formal)	σας αρέσει	ΣΑΣ ΑΡΕΣΕΙ
They like it	τους αρέσει	ΤΟΥΣ ΑΡΕΣΕΙ

And replace "αρέσει" with "αρέσουν" as before to like plural things

The above covers the way to say that you like things. Now we'll look at how to like doing things. This is really a combination of the "liking things" post and grammar post that I said had nothing to do with Year 1....how wrong I was! So when you like doing something the "something" you like doing is formed by using the subjunctive form of the verb.
So remember the subjunctive verb is just the normal verb with να/ΝΑ in front of it, and to like something we used μ'αρέσει/Μ'ΑΡΕΣΕΙ so putting it together we get:

• I like to write - μ'αρέσει να γράφω - Μ'ΑΡΕΣΕΙ ΝΑ ΓΡΑΦΩ

So remembering to take care with articles and plurals and verb endings etc. here are some examples to illustrate:

English	Lower	Upper
I like to work in the garden	μ'αρέσει να δουλευω στο κήπο	Μ'ΑΡΕΣΕΙ ΝΑ ΔΟΥΛΕΥΩ ΣΤΟ ΚΗΠΟ
We like to eat tasty food	μας αρέσει να τρώμε νόστιμα φάγητα	ΜΑΣ ΑΡΕΣΕΙ ΝΑ ΤΡΩΜΕ ΝΟΣΤΙΜΑ ΦΑΓΗΤΑ
Do you like to read books?	σ'αρέσει να διαβάζεις βιβλία	Σ'ΑΡΕΣΕΙ ΝΑ ΔΙΑΒΑΖΕΙΣ ΒΙΒΛΙΑ
Do you like to watch football?	σ'αρέσει να βλέπεις ποδόσφαιρο	Σ'ΑΡΕΣΕΙ ΝΑ ΒΛΕΠΕΙΣ ΠΟΔΟΣΦΑΙΡΟ
He likes to understand Greek	του αρέσει να καταλαβαίνει ελληνικά	ΤΟΥ ΑΡΕΣΕΙ ΝΑ ΚΑΤΑΛΑΒΑΙΝΕΙ ΕΛΛΗΝΙΚΑ

In the last example above (and the "reading books" one), even though it several animals he likes to understand as opposed to just one, technically it's the action of understanding animals that is being liked, not the animals themselves, and to understand has no quantity - it is neither singular nor plural. So, you always used the singular form of the verb (normally αρέσει) when talking about liking to do something.
