Unclear pronoun reference

One of 72 rules YabLab tracks in Russian writing.

A typical slip

Анна сказала Маше, что она устала.

Анна сказала Маше, что Маша устала.

The rule

Unclear pronoun reference

Word order and sentence structure tell the reader which ideas belong together and which information is new, emphasized or dependent.

Core order
Keep the clause skeleton visible Place the subject, verb and objects where the language expects them.
Dependencies
Keep related words together Modifiers, pronouns and particles should sit close to the words they describe.
Information flow
Order details deliberately Place, time and emphasis follow patterns that help the sentence read naturally.

What YabLab does with this mistake

  1. Catches it right as you write — comments, email, docs.
  2. Explains the why in your language, not just the fix.
  3. Helps you practice it until it is gone for good.
