Mistakes learners make (and what native speakers say)

1. Calling someone “stubborn” when you mean “persistent”

Learners often use stubborn as a compliment for someone who works hard and never quits. However, native speakers usually see stubborn as a negative trait. It means refusing to listen to good advice or to change your mind, even when you are wrong. If you want to praise someone’s strong effort, use persistent or tenacious.

Wrong: My sister is so stubborn! She studied every night and finally passed the bar exam.
Right: My sister is so persistent! She studied every night and finally passed the bar exam.

—

2. Using “to” + verb after “give up” instead of “-ing”

When you follow the phrasal verb give up with another action, always use the -ing form of the verb (give up smoking, never give up trying). Using to plus the base verb is a common mistake.

Wrong: I will never give up to learn English.
Right: I will never give up learning English.

—

3. Mixing up “give up” and “give up on”

Give up alone means to stop an action or habit. Adding the preposition on (give up on) changes the meaning to losing hope in a person, a team, or a long-term dream.

Wrong: A true leader will never give up their team during a crisis.
Right: A true leader will never give up on their team during a crisis.

—

4. Thinking “resilient” means physically flexible

Learners sometimes think resilient describes a person who can bend their body easily, like a gymnast. The word can describe materials, like rubber, that spring back into shape, but when native speakers use it about people, they mean recovering mentally and emotionally after hard times.

Wrong: He is very resilient because he can touch his toes without bending his knees.
Right: He is very resilient because he stayed positive and rebuilt his business after the fire.

—

5. Adding “am” before “give up”

Give up is an ordinary verb, so it does not need am in the present simple. Say I give up when you decide to stop right now, or I’m giving up for a change you are making (I’m giving up sugar).

Wrong: This puzzle is far too hard. I am give up.
Right: This puzzle is far too hard. I give up!

—

6. Saying “never give up” when someone actually needs to rest

Telling a struggling friend to “never give up” is not always helpful. Pushing through extreme tiredness can lead to burnout, and taking a short rest to recharge is not the same as quitting.

Wrong: You look sick and exhausted, but never give up! Keep working all night!
Right: You look exhausted. Get some rest tonight and try again tomorrow.
