bilgiyi

Bilgiyi is the Turkish definite accusative form of the noun bilgi, meaning information or knowledge. In Turkish sentences, bilgiyi functions as the direct object when referring to a particular piece of information. The form is produced by adding the definite accusative suffix -i (with appropriate vowel harmony) and inserting a linking consonant y because the stem ends in a vowel.

The Turkish accusative suffix follows vowel harmony: the form becomes -yi after a front vowel, giving bilgiyi; -ı or -u etc would appear with other stems. The linking consonant y helps to separate the object from the verb. Example sentences: Bilgiyi okuyorum (I am reading the information); Bilgiyi sakla (Hide the information); Bilgiyi bana ver (Give me the information).

In usage, bilgiyi typically refers to a specific piece of information understood from context; for generic information, other constructions are used (e.g., bilgi without suffix, or bir bilgi for “a piece of information”). The form also appears in fixed expressions and compound phrases. See also bilgi for the base noun and Turkish grammar for the accusative case.
