Russian cursive is the fully joined handwritten form of the Cyrillic alphabet taught in Russian schools, in which several letters turn into strokes so alike that words are read by context rather than letter by letter.
Letterforms
The handwritten letters differ from the printed ones more than in Latin script. Lowercase т becomes a shape like the Latin m, ш like w, and the two are told apart by a bar above т or below ш; и and п are both two strokes, г looks like a small hook, л and м begin with the same hook, and д is written like a Latin g. Capitals are rounded and close to the printed forms. The hand leans right and loops its descenders.
Joins and lifts
Every lowercase letter joins the next and the pen lifts only between words and for the bars on т and ш, the hook on й and the dots on ё. A word such as лишишь becomes a run of near-identical strokes, which is the feature of Russian cursive that non-native readers find hardest.
Where it comes from
The school script, the прописи, was standardised in the Soviet period and is still taught in the first year of Russian primary schools with practice books that drill each letter and its joins. Ukrainian, Belarusian, Bulgarian and Serbian cursives share most forms, with Serbian differing most in its т, п and г.
Copying and rendering it
There is no styled Cyrillic set in Unicode the way there is for Latin, so the copy-paste styles on this site do not apply to Russian text; real Cyrillic is copied exactly as typed. The Cyrillic cursive generator renders Russian text in the fonts on this site that carry Cyrillic and shows the confusable pairs side by side. The Cyrillic lookalike style on the fancy text generator is decoration for Latin text and corrupts real Russian.
Practising it
Russian children learn each letter in a прописи book with model, traced and independent rows; the same approach works for adults. Until an instructional Cyrillic face with stroke data is sourced there is no Russian worksheet pack here, so render a word in the generator, print it at worksheet size and copy it beneath on ruled paper.
