The grammatical categories of Albanian are much like those of other European languages. Nouns show overt gender, number, and three or four cases. An unusual feature is that nouns are further inflected obligatorily with suffixes to show definite or indefinite meaning; e.g., buk' "bread," buka "the bread." Adjectives--except numerals and certain quantifying expressions--and dependent nouns follow the noun they modify; and they are remarkable in requiring a particle preceding them that agrees with the noun. Thus, in nj' burr' i madh, meaning "a big man," burr' "man" is modified by madh "big," which is preceded by i, which agrees with the term for "man"; likewise, in dy burra t' m'dhenj"two big men," m'dhenj, the plural masculine form for "big," follows the noun burra "men" and is preceded by a particle t' that agrees with the noun. Verbs have roughly the number and variety of forms found in French or Italian and are quite irregular in forming their stems. Noun plurals are also notable for the irregularity of a large number of them. When a definite noun or one taken as already known is the direct object of the sentence, a pronoun in the objective case that repeats this information must also be inserted in the verb phrase; e.g., i-a dhash' librin atij is literally "him-it I-gave the-book to-him," which in standard English would be "I gave the book to him." In general, the grammar and formal distinctions of Albanian are reminiscent of Modern Greek and the Romance languages, especially of Romanian. The sounds suggest Hungarian or Greek, but Gheg with its nasal vowels strikes the ear as distinctive. Although Albanian has a host of borrowings from its neighbours, it shows exceedingly few evidences of contact with ancient Greek; one such is the Gheg moken; (Tosk mok'r) "millstone," from the Greek mekhane'. Obviously close contacts with the Romans gave many Latin loans; e.g., mik "friend," from Latin amicus; k'ndoj "sing, read" from cantare. Furthermore, such loanwords in Albanian attest to the similarities in development of the Latin spoken in the Balkans and of Romanian, a Balkan Romance tongue. For example, Latin paludem "swamp" became padulem, and then padure in Romanian and pyll in Albanian, both with a modified meaning, "forest."

Conversely, Romanian also shares some apparently non-Latin indigenous terms with Albanian; e.g., Romanian brad, Albanian bredh "fir." Thus these two languages reflect special historical contacts of early date. Early communication with the Goths presumably contributed tirq "trousers, breeches" (from an old compound "thigh-breech"), while early Slavic contacts gave gozhd' "nail." Many Italian, Turkish, Modern Greek, Serbian, and Macedonian-Slav loans can be attributed to cultural contacts of the past 500 years with Venetians, Ottomans, Greeks (to the south), and Slavs (to the east).

A fair number of features--e.g., the formation of the future tense and of the noun phrase--are shared with other languages of the Balkans but are of obscure origin and development; Albanian or its earlier kin could easily be the source for at least some of these. The study of such regional features in the Balkans has become a classic case for research on the phenomena of linguistic diffusion.
