If the word is followed by a verb, it is likely must.
Example: must + verb (go, study, finish).

✅ Tip 4: Think of Context

Perfume discussion? → musk
Rules or advice? → must

Context Matters

Understanding context is essential in English grammar. The correct word depends on the topic and sentence meaning.

Musk appears in discussions about:

• Fragrances
• Perfume ingredients
• Animal biology

Must appears in:

Exceptions To The Rules

Although the words are different in meaning, there are interesting linguistic notes.

This is a vocabulary exception because musk may appear in scientific or chemical contexts.

2. Winemaking

While musk is not common in wine terminology, some wines may be described as having a musk-like aroma. In this case, it refers to scent comparison, not grammar usage.

3. Idiomatic Expressions

The word must appears in idioms and fixed expressions such as:

• Must-have (something essential)
• Must-see (something important to watch)
• Must-read (essential reading)

Example:
This book is a must-read for students.

These expressions are common in American and British English and are widely used in marketing and reviews.
