Grammar for Speaking vs Writing: Know the Difference

Write the way you speak and it reads wrong; speak the way you write and it sounds stiff. Name the grammar area and this lays out the spoken and written forms side by side, explains when the wrong register grates, and tells you which forms to prioritise depending on whether you're chatting or drafting.

Explain the key grammatical differences between spoken and written registers in {TARGET_LANGUAGE}, focusing on {GRAMMAR_AREA}. For each difference: show an example of the spoken form and the written form side by side; explain when using the wrong register would sound unnatural or inappropriate; and note whether the spoken form is considered non-standard or simply informal. Include guidance on which forms to prioritise if my goal is {LEARNING_GOAL} (e.g. passing an exam, having casual conversations, writing professional emails). My current level is {PROFICIENCY_LEVEL}.
