• In Turkish, we have a simple present tense, but we usually use present continuous tense instead of it. So we don't say "I love you". In Turkish it becomes "I'm loving you" in daily life. (Actually Turkish people are generous about love, so we say "I would be sacrifice for you" or "Let me die for the God that created you" :) )

• Well, so let's check what we learned until today and then making a sentence in present continuous tense will be easier.

We learned how to say "I loved". It was "Ben sevdim." But we don't use the pronounce when we don't stress the person. So it becomes "Sevdim."

• Now look at the table below and let's say "I loved you." As you see here, "you" is in object position, so we'll use second column.
• Predicate is always at the end of the sentence in Turkish, so we'll add our "you" word before the predicate. So literally it will be "(I) you loved"

(Ben) seni sevdim.
I loved you.
(Ben) onu sevdim.
I loved her.
(Sen) onu sevdin.
You loved her.
(Sen) beni sevdin.
You loved me.

•  Now let's learn present continuous tense. Our suffix is "-yor" means "-ing" in English.

Let's check "I am reading." (Remember read: oku)

Ben oku-yor-um
I am reading

Don't memorize it. You know the rule. Remember what was happening in past tense.***

Ben oku-du-m.

• Here when you see "o" or "u" vowel, you were adding "-du". In present continuous, it's same. We have "o" vowel in "yor" suffix, so we use "u" vowel.

After we understood why we use "u", let's learn other persons:

Ben oku-yor-um              I am reading
Sen oku-yor-sun             You are reading
O oku-yor                   He/She/It is reading
Biz oku-yor-uz              We are reading
Siz oku-yor-sunuz           You are reading
Onlar oku-yor-(lar)         They are reading

Now see the similarities and differences with simple past tense:

Ben oku-du-m                I read (past)
Sen oku-du-n                You read
O oku-du                    He/She/It read
Biz oku-du-k                We read
Siz oku-du-nuz              You read
Onlar oku-du-(lar)          They read

• Did you see the similarities singular and plural forms of "you" ? Let's see that simple word and compare others:

Sen sev-di-n.                      You loved (singular)
Siz sev-di-niz.                    You loved (plural)

Let's check you're reading and you read:

• Sen oku-yor-sun,             You're reading (singular)
• Siz oku-yor-sunuz.          You're reading (plural)
• Sen oku-du-n                    You read (singular, past simple)
• Siz oku-du-nuz.                You read (plural, past simple)

***If you didn't realize why we use "u" here and at the beginning of our rules for present continuous, let's remember this rule from Lesson 3:

a, ı -> ı      Aldı. Kırdı. 
e, i -> i      Geldi. Sildi.
o, u -> u      Oldu. Uyudu. 
ö, ü -> ü      Öldü. Güldü.

Just one step remaining for being ready to say "I love you": If a verb ends with a vowel, it's ok. Just add -yor and change it depending on person. But if a verb ends with a consonant, you should add a vowel. But which vowel? Look at the rule from Lesson 3. It's the same:

a, ı -> ı      Alıyor. Kırıyor.
e, i -> i      Geliyor. Siliyor.
o, u -> u      Oluyor. Uyuyor. (In Uyuyor, it is already ended with vowel)
ö, ü -> ü      Ölüyor. Gülüyor.

• You know how to say I loved you, rule is same. Bring "you" before the predicate.

(Ben) seni seviyorum.
I love you. (Literally: (I) am loving you)

Onu seviyorum.     I love her/him/it
Onu seviyorsun.    You love her/him/it
Beni seviyorsun.   You love me
Seni seviyor.      He/She/It loves you
Onları seviyoruz.  We love them
Bizi seviyorlar.   They love us

Let's review: We know we don't use pronoun as subject. We use present continuous instead of present simple. Lesson 5: Language is Not Grammar
