Learn Turkish: Sağ avucun kaşınırsa para gelir. - If your right palm itches, money comes.

It uses the Aorist tense plus the conditional suffix, which is the pattern for 'if it happens'. The verb is kaşınmak (to itch). First, we add the Aorist suffix -ır to get kaşınır (it itches), and then the conditional -sa to get kaşınırsa (if it itches).

Why does the sentence use the Aorist tense (gelir) instead of the present continuous (geliyor)?

Gelir is the Aorist form of gelmek (to come). The Aorist tense is used for general facts, habits, and timeless statements. Because this is a traditional superstition (a general rule that people believe happens every time), the Aorist is the natural choice here.

Why is there a 'c' in avucun (your palm) if the dictionary word for palm is avuç?

This is an example of consonant mutation. When you add a suffix that starts with a vowel, like the 'your' suffix -un, the hard ç at the end of avuç softens to a c to make it easier to pronounce.

What is the difference between kaşımak and kaşınmak?

Kaşımak is an active verb meaning 'to scratch' (like scratching a mosquito bite). Adding the -n makes it kaşınmak, which means 'to itch' or 'to feel itchy'. In this sentence, the palm isn't scratching anything; it is experiencing the itch!
