-ti/-tı

Past Ending After Voiceless Consonants

Level 2

The -ti/-tı/-tu/-tü suffix is the past tense form used when a verb stem ends in a 'hard' (voiceless) consonant. It indicates an action that definitely happened, often witnessed by the speaker.

How It Works

The -ti/-tı pattern is a variant of the Simple Past Tense. It is used for actions completed in the past where the speaker witnessed the event, is certain of the result, or is stating objective historical facts (e.g., Atatürk 1881'de doğdu).

1. The 'Hardening' Rule:
If a verb stem ends in one of the eight voiceless consonants (f, s, t, k, ç, ş, h, p), the suffix 'd' changes to 't'. This is known as consonant assimilation.

2. Vowel Harmony:
This suffix follows the Four-Way Vowel Harmony system (Dörtlü Ünlü Uyumu):

  • -tı: after a, ı (e.g., baktı)
  • -ti: after e, i (e.g., gitti)
  • -tu: after o, u (e.g., koştu)
  • -tü: after ö, ü (e.g., düştü)

3. Adding Person Endings:
To say who did the action, you must add simple past person endings after the tense suffix:

  • Gittim (I went)
  • Gittin (You went)
  • Gitti (He/She/It went)
  • Gittik (We went)
  • Gittiniz (You all went)
  • Gittiler (They went)

4. Negatives and Questions:
To make the verb negative, use -medi/-madı. Note that because the negative suffix ends in a vowel, the 'd' does not harden to 't' (e.g., gitmedi). To ask a question, place the question word after the conjugated verb (e.g., Gittin mi?). The particle is always written as a separate word.

5. Usage Nuance:
Use this when you are sure of the information or stating definite facts. However, for actions performed unconsciously, -miş is preferred. If you didn't see it happen and it is not a known fact, use reported past instead.

Examples (5)

  1. Dün akşam çok çalıştım.

    I worked a lot last night.

    Word by Word: Yesterday evening much work-past-I.

    The verb stem 'çalış-' ends in 'ş' (voiceless), so the suffix becomes '-tı' instead of '-dı'.

  2. Ali kapıyı açtı.

    Ali opened the door.

    Word by Word: Ali door-acc open-past.

    The stem 'aç-' ends in 'ç', triggering the change to '-tı'.

  3. Kedi süte baktı.

    The cat looked at the milk.

    Word by Word: Cat milk-dat look-past.

    The stem 'bak-' ends in 'k', so we use '-tı'.

  4. Otobüsten düştü.

    He/she fell from the bus.

    Word by Word: Bus-from fall-past.

    The stem 'düş-' ends in 'ş' and the last vowel is 'ü', so the suffix is '-tü'.

  5. Süt içti.

    He/she drank milk.

    Word by Word: Milk drink-past.

    The stem 'iç-' ends in 'ç', so the suffix is '-ti'.

Common Mistakes

  • Using the voiced '-di' after a voiceless consonant.

    gitdi
    gitti

    Because 't' is a voiceless consonant, the suffix must 'harden' to match it. Writing 'gitdi' is a spelling error.

  • Forgetting vowel harmony.

    yapti
    yaptı

    The verb 'yap-' contains the vowel 'a', so according to four-way vowel harmony, the suffix must be '-tı', not '-ti'.

Learn This First

To understand why the past tense suffix changes from -di to -ti, you first need to be familiar with the basic simple past tense. You must also understand the rules of consonant assimilation (ünsüz benzeşmesi), which explains the shift from 'd' to 't' after voiceless consonants (p, ç, t, k, f, h, s, ş), and four-way vowel harmony to choose the correct vowel for the suffix.
