Suffixes identify different relationships

A class compares the original examples “Öğrenciler okulda”, “Öğrenciler okula gidiyor” and “Öğrenciler okuldan geliyor”. One learner translates all three simply as students and school, overlooking the case endings. Another recognizes -da, -a and -dan but assumes they can be freely exchanged because the same place is involved. The teacher asks learners to explain location, direction and source in these sentences and then compare “Kitabı okudum” with a non-specific reading statement. The exercise does not establish a universal English-to-Turkish object rule, and no audio demonstrates intonational focus. Each example is an original classroom sentence. A useful explanation should connect the full construction to meaning rather than identify a suffix in isolation and assume that all verbs or postpositions take identical case marking.
