Turkish is an agglutinative language and frequently uses affixes, and specifically suffixes, or endings. One word can have many affixes and these can also be used to create new words, such as creating a verb from a noun, or a noun from a verbal root (see the section on Word formation). Most affixes indicate the grammatical function of the word. The only native prefixes are alliterative intensifying syllables used with adjectives or adverbs: for example sımsıcak (“boiling hot” < sıcak) and masmavi (“bright blue” < mavi).
The extensive use of affixes can give rise to long words. It is jokingly said that the longest Turkish word is Çekoslovakyalılaştıramadıklarımızdanmışsınız, meaning “You are said to be one of those that we couldn’t manage to convert to a Czechoslovak”. This example is of course contrived; but long words do frequently occur in normal Turkish, as in this heading of a newspaper obituary column: Bayramlaşamadıklarımız (Bayram [festival]-Recipr-Impot-Partic-Plur-PossPl1; “Those of our number with whom we cannot exchange the season’s greetings”). Another example can be seen in the final word of this heading of the online Turkish Spelling Guide (İmlâ Kılavuzu): Dilde birlik, ulusal birliğin vazgeçilemezlerindendir (“Unity in language is among the indispensables [dispense-Pass-Impot-Plur-PossS3-Abl-Copula] of national unity ~ Linguistic unity is a sine qua non of national unity”).
