take suffixes that assign person: for example -imiz 4, "our". With the addition of the copula (for example -im 4, "I am") complete sentences can be formed. The interrogative particle mi 4 immediately follows the word being questioned, and also follows vowel harmony: köye mi? "[going] to the village?", ağaç mı? "[is it a] tree?". Personal pronouns The Turkish personal pronouns in the nominative case are ben (1s), sen (2s), o (3s), biz (1pl), siz (2pl, or 2h), and onlar (3pl). They are declined regularly with some exceptions: benim (1s gen.); bizim (1pl gen.); bana (1s dat.); sana (2s dat.); and the oblique forms of o use the root on. As mentioned before, all demonstrative singular and personal pronouns take the genitive when ile is affixed onto it: benimle (1s ins.), bizimle (1pl ins.); but onunla (3s ins.), onlarla (3pl ins.). All other pronouns (reflexive kendi and so on) are declined regularly. Noun phrases (tamlama) Two nouns, or groups of nouns, may be joined in either of two ways: definite (possessive) compound (belirtili tamlama). E.g. Türkiye'nin sesi "the voice of Turkey (radio station)": the voice belonging to Turkey. Here the relationship is shown by the genitive ending -in4 added to the first noun; the second noun has the third-person suffix of possession 4. indefinite (qualifying) compound (belirtisiz tamlama). E.g. Türkiye Cumhuriyeti "Turkey-Republic = the Republic of Turkey": not the republic belonging to Turkey, but the Republic that is Turkey. Here the first noun has no ending; but the second noun has the ending 4—the same as in definite compounds. The following table illustrates these principles. In some cases the constituents of the compounds are themselves compounds; for clarity these subsidiary compounds are marked with [square brackets]. The suffixes involved in the linking are underlined. Note that if the second noun group already had a possessive suffix (because it is a compound by itself), no further suffix is added. As the last example shows, the qualifying expression may be a substantival sentence rather than a noun or noun group. There is a third way of linking the nouns where both nouns take no suffixes (takısız tamlama). However, in this case the first noun acts as an adjective, e.g. Demir kapı (iron gate), elma yanak ("apple cheek", i.e. red cheek), kömür göz ("coal eye", i.e. black eye) : Adjectives Turkish adjectives are not declined. However most adjectives can also be used as
