Ben sabah erken kalkmaya alışkınım.

alışkınım translates as “I am accustomed to” or “I’m used to.” It’s built from:

• alış (root from the verb alışmak, “to get used to”)
• -kın (adjectival suffix, forming alışkın, “accustomed”)
• -ım (first-person singular possessive/copylar suffix, “my is,” functioning here as “I am”)

So literally it’s “my being accustomed,” i.e. “I am accustomed.”

After alışkın (“accustomed”), Turkish requires a noun in the dative case to show “to doing something.” The steps are:
1) kalk = verb root “get up”
2) -ma = verbal-noun (deverbal) suffix, yields kalkma “the act of getting up”
3) -ya = dative case marker, yields kalkmaya “to the act of getting up”

Hence kalkmaya = “to getting up,” equivalent to English “to get up” in “used to get up.”

Turkish conjugations do mark the subject (here -ım in alışkınım marks “I”). Still, speakers often include pronouns like Ben for:
• Emphasis (“I, personally…”)
• Contrast (“I do, but others don’t…”)
• Clarity in longer or more complex sentences

You can drop Ben and still be correct: Sabah erken kalkmaya alışkınım.

• sabah can function as an adverb meaning “in the morning”
• erken is an adverb meaning “early”

In Turkish, you’ll often see the broader time expression first, then the manner: sabah erken (“in the morning, early”). Erken sabah is also possible but shifts nuance to “early morning” as a single time chunk (e.g. erken sabah yatak başında bekledim – “I waited by the bed in the early morning”).

• alışmak + (–A) is a verb meaning “to become accustomed to,” e.g. Kahve içmeye alıştım. (“I got used to drinking coffee.”)
• alışkın olmak turns it into an adjective phrase: “to be accustomed.” In practice you often drop olmak and use the adjective + suffix, as in alışkınım.

Using alışmak focuses on the process of getting used to something; alışkın emphasizes the resulting state (“I’m accustomed”).
