To enhance Emir's answer; Simple Structures: Konuşurum : I speak Konuşuyorum : I am speaking Konuştum : I spoke / I have spoken Konuşmuşum : I spoke / I have spoken (but I don't remember or I wasn't aware of it) Konuşacağım : I will speak Combined tenses with -di Konuşurdum : I used to speak / I would speak Konuşuyordum : I was speaking Konuşmuştum : I had spoken Konuştuydum : I had spoken (Very colloquial language. Don't use this, prefer Konuşmuştum) Konuşacaktım : I was going to speak Combined tenses with -miş: Konuşurmuşum : I used to speak (I learnt it later, I didn't know/remember before) Konuşuyormuşum : I was speaking (I learnt it later, I didn't know/remember before) Konuşmuşmuşum : (Some claim) I spoke / I have spoken (but I don't believe it much) Konuşacakmışım: I was going to speak (I learnt it later, I didn't know/remember before) -miş past tenses are not suitable for 'I' sometimes. It's used for cases that the speaker heard/learnt it later but generally you know/remember what you did in the past.

present simple: konuşurum present continuous: konuşuyorum past definite: konuştum past continuous : konuşuyordum future simple: konuşacağım

check the Turkish words in en.wiktionary.org indeed, we can write some verbs in all tenses, too. but all them seem difficult and complicated to you then, because you haven't learnt any of the tenses. before thinking about all tenses together, i recommend you to learn the tenses one by one first. :)

EDIT: My bad, wrong language
