Morphology and syntax
Much of the inflectional apparatus of the ancient language is retained in Modern Greek. Nouns may be singular or pluralâthe dual is lostâand all dialects distinguish a nominative (subject) case and accusative (object) case. A noun modifying a second noun is expressed by the genitive case except in the north, where a prepositional phrase is usually preferred. The indirect object is also expressed by the genitive case (or by the preposition se âto,â which governs the accusative, as do all prepositions). Thus:

The ancient categorization of nouns into masculine, feminine, and neuter survives intact, and adjectives agree in gender, number, and case with their nouns, as do the articles (o âthe,â enas âaâ). In general, pronouns exhibit the same categories as nouns, but the relative pronoun pu is invariant, its relation to its own clause being expressed when necessary by a personal pronoun in the appropriate case: i yinĂ©ka pu tin Ădhe to korĂtsi âthe woman pu her saw the girlâ (i.e., âthe woman whom the girl sawâ).
The verb is inflected for mood (indicative, subjunctive, imperative), aspect (perfective, imperfective), voice (active, passive), tense (present, past), and person (first, second, and third, singular and plural). The future is expressed by a particle tha (from earlier thĂ©[o] na â[I] want toâ) followed by a finite verbâe.g., tha grĂĄpho âI will write.â Formally, the finite forms of the verb (those with personal endings) consist of a stem + (optionally) the perfective aspect marker (-s- in active, -th- in passive) + personal ending (indicating person, tense, mood, voice). Past forms are prefixed by e- (the âaugmentâ), usually lost in mainland dialects when unstressed. There are also two nonfinite forms, an indeclinable present active participle in -ondas (ghrĂĄfondas âwritingâ), and a past passive one in -mĂ©nos (kurazmĂ©nos âtiredâ).
Aspectual differences play a crucial role. Roughly, the perfective marker indicates completed, momentary action; its absence signifies an action viewed as incomplete, continuous, or repeated. Thus the imperfective imperative ghrĂĄphe might mean âstart writing!â or âwrite regularly!â while ghrĂĄpse means rather âwrite down! (on a particular occasion).â Compare also tha ghrĂĄpho âIâll be writingâ but tha ghrĂĄpso âIâll write (once).â The difference is sometimes represented lexically in English: ĂĄkuye âhe listenedâ and ĂĄkuse âhe heard.â The passive forms are largely confined to certain verbs active in meaning like Ă©rkhome âI come,â fovĂĄme âI am afraid,â and reciprocal usages (filyĂłndusan âthey were kissingâ).
The most common form of derivation is by suffixation; derivation by prefixation is limited mainly to verbs. On the other hand, compound formation is rich. Three morphological types of compounds can be distinguished, as reflected also in their stressingâthus, stem + stem compoundsâe.g., palyĂłfilos âold friendâ (o is the compound vowel) or khortofĂĄghos âvegetarianâ; stem + word compoundsâe.g., palyofĂlos âlousy friendâ (compare fĂlos âfriendâ); and the newly borrowed formation, word + word compoundsâe.g., pedhĂ thĂĄvma as English âboy wonder.â There is no infinitive; ancient constructions involving it are usually replaced by na (from ancient hĂna âso thatâ) + subjunctive. Thus thĂ©lo na ghrĂĄpso âI want to write,â borĂ na ghrĂĄpsi âhe can write.â Subordinate statement is introduced by Ăłti or pos (lĂ©i Ăłti fĂ©vghi âhe says that he is leavingâ). Unlike English, Greek (because of its inflectional system) shows flexible word order even in the simplest sentences. Further, as in Italian, the subject of a sentence may be omitted.
Vocabulary
The vast majority of Demotic words are inherited from Ancient Greek, although quite often with changed meaningâe.g., filĂł âI kissâ (originally âloveâ), trĂłgho âI eatâ (from ânibbleâ), kĂłri âdaughterâ (from âgirlâ). Many others represent unattested combinations of ancient roots and affixes; others enter Demotic via Katharevusa: musĂo âmuseum,â stikhĂo âelementâ (but inherited stikhyĂł âghostâ), ektelĂł âI execute.â In addition, there are more than 2,000 words in common use drawn from Italian and Turkish (accounting for about a third each), and from Latin, French, and, increasingly, English. The Latin, Italian, and Turkish elements (mostly nouns) acquire Greek inflections (from Italian sĂghuros âsure,â servitĂłros âservant,â from Turkish zĂłri âforce,â khasĂĄpis âbutcherâ), while more recent loans from French and English remain unintegrated (spor âsport,â bar âbar,â asansĂ©r âelevator,â futbĂłl âfootball,â kompyĂșter âcomputer,â tĂ©nis âtennisâ).
