Questions & Answers about Bu akşam iyice yorgunum, bu yüzden evde kalıyorum.

Why does yorgunum mean I am tired? Where is the verb to be?

In Turkish, present-tense to be is often expressed with a personal ending instead of a separate verb.

• yorgun = tired
• -um = I am / first-person singular ending

So:

• yorgunum = I am tired

This is very common with adjectives and nouns:

• mutluyum = I am happy
• öğrenciyim = I am a student

So Turkish does not need a separate word for am here.

Why is it yorgunum, not yorgunim?

Because of vowel harmony.

The personal ending here changes to match the last vowel of the word:

• last vowel in yorgun is u
• after u, the matching form is -um

So:

• yorgun + um → yorgunum

Compare:

• iyiyim = I am well
• üzgünüm = I am sad
• hazırım = I am ready

The ending changes shape depending on the vowels in the word before it.
