Learn Turkish: Burada bekleme odası yok. - There is no waiting room here.

You are right that -me is also the negative suffix for verbs (like bekleme! meaning 'don't wait!'). However, in this lesson, -me or -ma is used to turn a verb into a conceptual noun. You can tell it is a noun here because it is grouped with odası (room) to make the noun compound bekleme odası (waiting room).

Why use the short infinitive bekleme instead of the full infinitive beklemek?

When we create compound nouns in Turkish using a verb action (like 'waiting room' or 'swimming pool'), we always use the short infinitive (-ma or -me) for the first part, not the full infinitive (-mak or -mek). So it is always bekleme odası, never beklemek odası.

Why does oda have the -sı suffix at the end?

This is the standard rule for forming noun compounds in Turkish. When two nouns are joined to make a specific new concept (like bekleme and oda), the second noun takes a possessive suffix. Since oda ends in a vowel, it takes -sı, making it bekleme odası (literally 'waiting its-room').

Why do we use burada instead of just bura for 'here'?
