Questions & Answers about Dün partide çok sıkıldım ve yoruldum.
Why do sıkıldım and yoruldum end in -m instead of -im or -um like present tense verbs do?
The past tense uses a special set of personal endings. For the "I" form, you don't use a vowel like you do in the present tense. Instead, you just attach an -m directly to the past tense suffix.
Why is the past tense suffix -dı in sıkıldım but -du in yoruldum?
This is due to 4-way vowel harmony. The past tense suffix changes to match the last vowel of the verb root. The verb root sıkıl- has an ı, so it takes -dı. The verb root yorul- has a u, so it takes -du.
In English, "bored" and "tired" are adjectives. Are they verbs in Turkish?
Exactly! In Turkish, sıkılmak (to get bored) and yorulmak (to get tired) are action verbs. You aren't saying "I was tired," you are actually saying "I got tired" and "I got bored". That is why they take standard verb past tense suffixes.
