Headless Relative Clauses
When describing a noun with a relative participle, such as kazandığım para (the money I earned) or alacakları hisse (the share they will buy), you can drop the noun if context makes it obvious.
The participle then acts as a noun itself. In English, this translates to "what" (e.g., "what I earned", "what they will buy"). Because it acts as a noun, the participle directly takes any required case endings.
Past and Present: -DIk
To express "what I did" or "what she bought," use the -DIk participle with a possessive suffix.
When the headless clause is the direct object of a verb, add the accusative case ending to its possessive suffix.
When it acts as the subject, it needs no extra case ending.
Plurals with Headless Participles
To refer to plural objects ("the things"), insert the plural suffix (-lAr) right after the participle and before the possessive suffix.
al (to buy) + dık (participle) + lar (plural) + ım (my) + ı (accusative) = aldıklarımı (what I bought / the things I bought)
For "what I will do" or "what you will earn," use the future participle -(y)AcAk without a noun. Like -DIk, it takes possessive suffixes and appropriate case endings.
Putting It Together
Headless relative clauses are extremely common in Turkish, especially when the specific object (like "money," "amount," or "currency") is already understood.
