Critical Nuance — Stative Verbs
⚠️
Critical Rule — Action vs. Stative Verbs

Certain verbs describe a state (thinking, feeling, possessing, sensing) rather than a physical action. These verbs are strictly not used in continuous tenses at B1 level.

❌ I am knowing the answer.
✅ I know the answer.
🔄 Dynamic Stative Verbs — Dual Meanings

Some verbs change their meaning depending on whether they appear in Simple or Continuous form:

THINK
State — Opinion
"I think this platform is amazing."
Action — Mental Process
"Quiet please, I am thinking about how to solve this bug."
HAVE
State — Possession
"She has a premium subscription."
Action — Activity
"He is having lunch at the moment."
