Russian cursive can be challenging for beginners because many handwritten letters look different from their printed Cyrillic forms. Connected strokes and similar-looking characters can make reading difficult until learners become familiar with the writing style.
A helpful way to practice is to compare printed Cyrillic letters with cursive-style fonts. This allows learners to recognize different letter shapes and gradually improve their reading skills.
