Helsinki slang
Helsinki slang or stadin slangi ("Helsinki's slang", from Swedish , "city"; see etymology) is a local dialect and a sociolect of the Finnish language mainly used in the capital city of Helsinki. It is characterized by its abundance of foreign loan words not found in the other Finnish dialects. Helsinki slang first evolved in the late 19th century as a sociolect of the multilingual Helsinki working class communities, where Swedish and Finnish speaking youth lived together with Russian, German and various other language minorities. Helsinki slang is not a typical dialect of Finnish, because unlike many other parts  of Finland, the Helsinki area was predominantly Swedish-speaking during the time when the city of Helsinki originally evolved, and thus Helsinki slang is characterised by an unusual, strikingly large number of obvious foreign loanwords. Nevertheless, Helsinki slang is counted as a dialect on its own right, among the "purer" dialects of other parts of Finland. Grammatically Helsinki slang is based on colloquial Finnish. It is characterized by a large number of words originally borrowed from Swedish, German and Russian, but nowadays chiefly English. The loanwords replace some of even the most mundane Finnish-language words (closest kin words, "food , die" etc.) with foreign alternatives. However, when spoken by a native Finnish speaker, all words are inflected by the rules of spoken Finnish, and the language sounds distinctively Finnish. The language's history can generally be divided into the 'old' slang () and the 'new' or 'modern' slang (). Old slang was common in Helsinki up to the mid-20th century, and is thicker and harder to understand for an outsider of the group, even to one who would be capable in modern slang, because it incorporates a far greater number of Swedish and Russian loan-words than the modern variation. Old slang  is mostly spoken by older Helsinkians, many of whom consider it the only true slang. The modern variety has evolved side-by-side with the growing influence of English-language youth subcultures starting from the 1950s. It is thus characterized by a greater influence of the English language and proper Finnish language while the influence of Swedish and Russian has declined. The modern slang is healthy and continues to evolve. It is spoken to varying degrees by almost all native Helsinkians. Etymology. Helsinkians themselves never refer to their slang as "Helsinki slang(i)" but instead as "stadin slangi" or simply "slangi . Stadi" is a slang word itself, borrowed from the Swedish "stad", "city". Literally, the name would mean "slang of the city", but "stadi" always means just the city of Helsinki in the slang – all other cities are unconditionally referred to by the common Finnish word for "city" ("kaupunki"). More importantly, Helsinki slang is not strictly speaking a slang in the word's modern definition, but rather a dialect and a sociolect. However, the term "slang" has stuck since long, especially as the language refers to itself as "slangi". History. Roots in the 1880s. Helsinki was founded in 1550 by Gustav  I of Sweden in the coastal Swedish-speaking region of Finland. When in 1809 Sweden lost Finland to Imperial Russia, Helsinki became the capital of Finland by the decision of Alexander I of Russia. At this time, Helsinki was almost unilingually Swedish. In 1820, for example, the city was home to about 4,500 people, only 5% of whom were Finnish-speaking. With the new capital status, the city's centre was rebuilt and a continuous growth was sustained. By 1880 the population had grown almost ten-fold to 43,000, mostly due to industrialization. This brought ever-increasing numbers of new  Finnish-speaking working class from around the country to the largely Swedish-speaking city. In the 1870 census 57% of Helsinkians spoke Swedish as their home language, 26% Finnish, 12% Russian and 2% German, while also increasing numbers of residents were capable in both Swedish and Finnish. Helsinki slang is believed to have first began to evolve among the mixed-language working-class people of the 1880s. In addition to Swedish and Finnish, influence came from Russian and German. Helsinki slang is thought to have formed naturally as a sort of a common language for the mixed-language population who  due to industrialization moved into the same neighbourhoods for employment, and had no single common language initially. The slang came to be for practical purposes of everyday communication and mutual understanding as a common language of the various language groups. For example, at this time about one fifth of newly-wed couples had different native languages. The working class population was at this time concentrated in Kallio, Vallila, Sörnäinen and Arabia. Helsinki slang was probably first born in these tightly populated neighbourhoods in their factories, multilingual homes, markets and on their streets. Some have referred to "slangi"'s roots as  a pidgin language or the "lingua franca" of this multilingual population. Youth's language. From early on Helsinki slang was especially the language of the youth. It could be thought as a social language code, by which the multicultural and multilingual working class youth, a speech community, formed their own sociolect. The initiative for this grew at first from their needs of basic everyday communication, but soon "slangi" probably came to signify a certain social status as well. Johannes Kauhanen notes on his slang history page that the first speakers of Helsinki slang were probably not the countryside-born agriculturists  who moved to work in Helsinki, but their children. The first known written account in Helsinki slang is from the 1890 short story "Hellaassa" by young Santeri Ivalo (words that do not exist in, or deviate from, the standard spoken Finnish of its time are in "italics"): Kun minä eilen illalla palasin "labbiksesta", tapasin "Aasiksen" kohdalla "Supiksen", ja niin me laskeusimme tänne "Espikselle", jossa oli mahoton hyvä "piikis". Mutta me mentiin "Studikselle" suoraan "Hudista" tapaamaan, ja jäimme sinne pariksi tunniksi, kunnes ajoimme "Kaisikseen". Modernization. The "old slang" continued to develop up until the 1940s. In 1944 the Continuation War between  the Soviet Union and Finland ended in the Moscow Armistice, and Finland had to cede large parts of Karelia to the Soviet Union. About 430,000 people became refugees within their own country. Many of them settled in Helsinki while, in the society at large, the transition from the agricultural society continued ever stronger. In practice the following years, especially the 1960s, meant the second major wave of immigration to Helsinki. This had an effect on the slang as well. 1940s mark the beginning of the gradual transition between the old slang ("vanha slangi") and modern speech ("uusi slangi"). The new  population was, and continues to be, in greater numbers Finnish-speaking, and the Swedish and Russian influences on the language have declined ever since. The language started to move more towards common colloquial Finnish while still strongly borrowing from the old slang. The following generations also grew up in a different kind of cultural environment, where more abundant amounts of foreign culture, especially entertainment such as films and music, was, and continues to be, available. The cultural influence of the English-speaking world, especially the North American youth subcultures, grew, and increasing numbers of English-language words started to find  their way to the language of the urban Helsinki youth. With the popularity of television and the advent of the Internet, this trend continues ever stronger in the present day. Evolution. Although like any local dialect, Helsinki slang constantly evolves, most adult speakers of Helsinki slang still consider the pre-1960s version the "real" slang. Many of the now-adult speakers who grew up with the 1950s-style slang consider the modern chiefly English-derived slang terms neologisms. Nevertheless, even if words are borrowed to the slang, they are still in the present day modified to conform to the phonotactics of  the slang. As noted below, the phonotactics are slightly different from typical colloquial Finnish. Language characteristics. The borrowed words may violate phonological rules of the Finnish language, such as vowel harmony. They also include phonemes /b/, /d/ and /g/ and consonant clusters such as /sn/ rarely found in other Finnish dialects. Yet the words remain indisputably Finnish, incorporating Finnish grammar and mostly obeying Finnish phonotactics. Some rather arbitrary, but creative and distinctly Finnish expressive constructions are often used especially in the modern slang, e.g. "päräyttää". Furthermore, arbitrary modifications are found — these make the resulting slang words alien both to the  speakers of regular Finnish and the borrowing language. For example, Finland Swedish (Sipoo dialect) "burk" "cranky" is modified into "spurgu" "drunkard", where the added 's' is arbitrary, as is the voicing change of 'k' to 'g'. Derivation of "fillari", "a bicycle" from "velociped" is even more convoluted: "velociped" in the Swedish language game "fikonspråk" is "filociped-vekon", which became "filusari" and further "fillari" — only the 'l' is etymologically original. In fact, the newer abbreviation of "fillari" to "fiude" loses even the 'l'. Some distinctive aspects in Helsinki slang are: Variation. The old slang's vocabulary and form of speech had  some variation in between different parts of the town. As noted above, the language was born north of the Pitkäsilta bridge, but it later spread to the southern neighborhoods as well, including Punavuori ("Rööperi" in slang). The variation was most prominent in between the slang spoken on the two sides of the bridge. Usage and examples. Many literary works in Helsinki slang contain long sentences with a large density of slang words, making them especially hard to decipher for the general Finnish-speaking population. Examples where the slang words are in "italics" and in the same order in both the  original and translation follow: Slang words obey normal Finnish grammar, regardless of their etymology. However, Helsinki slang is always both spoken and written as colloquial Finnish, never as properly grammatical "kirjakieli" (see spoken Finnish). For example, "can you fix that in a working condition?" is ""voitsä duunaa ton kondiksee?"" in slang, where "duunaa", "to do, to work" and "kondis", "condition, working order" are slang words. Trying to write the above sentence in properly grammatical form like in kirjakieli, to ""voitko (sinä) duunata tuon kondikseen?"" would be erroneous both in kirjakieli and slang. Helsinki slang is also used by the Swedish -speaking Finnish minority in Helsinki. Modern Helsinkian Swedish-based slangi is still spoken in the same manner as in Finnish, mixing it into the Swedish language. The earlier example "can you put that in order?" would be ""kan du duuna dendä' kondiksee?"" when spoken by a Swedish-speaking Finn in Helsinki slang. The same sentence would be similarly erroneous in proper Finland Swedish language as well. Famous speakers. Several famous Helsinkians, especially musicians, are known for their skill in the slang, and have partially or entirely performed in it in public. Literature. Several books and comics have been published written  entirely in Helsinki slang, both as translations and as newly authored texts, or something in between. This is only a partial list, slanted towards the modern times.
