Tips for giving better compliments in English

1. Be specific

Specific compliments seem more authentic. Instead of:

 You are amazing. Try:  You always inspire people with your optimism.

2. Focus on actions

A positive verb highlights deeds executed by the individual rather than their character traits. Like:

 He influences others through kindness and patience.

3. Use natural situations

Compliments are more motivating when associated with real-life situations. Such as:

 Your advice really illuminated the problem for me.

The right verb can make a simple compliment sound warm and memorable. 

Tricky “I” verbs: regular vs. irregular

The English verbs that start with “I” may seem confusing because the past tense is not always formed in the same way. Some verbs simply add -ed, while others keep the same form in both the present and past tense. This difference in forming the past tense often causes mistakes for English learners. 

For instance, most of them are regular verbs starting with “I,” meaning they adhere to the usual formation pattern of verbs:

  • Base Verb + -ed
  • Inform → informed
  • Influence → influenced

Yet, there are certain exceptions to the rule regarding irregular verbs that start with “I.”

For example:

  Yesterday, he input the information into the database.
  The scenes were intercut for dramatic effect.

Both input and inputted are accepted in modern English, although input is more common in technical writing.

Common mistakes in the use of verbs with “I”

Because some verbs that start with “I” have similar meanings or unusual grammar patterns, learners often make small mistakes when speaking or writing English. Below are several common errors and their correct forms.

Confusing invent and invest

These verbs sound similar but have completely different meanings.

Incorrect Correct
  The company invented millions in new technology.
  The company invested millions in new technology.
  He invested a new mobile application last year.
  He invented a new mobile application last year.
Tip: 

Invent = create something new; invest = put money, time, or effort into something.

Using the wrong structure with inform

The verb inform usually needs an object before the topic.

Incorrect Correct
  They informed about the delay yesterday.
  They informed us about the delay yesterday.
  The manager informed to employees about the meeting.
  The manager informed employees about the meeting.
Tip: 

Use: inform someone about something, inform someone of something.

Adding unnecessary prepositions after influence

Many learners incorrectly use on after the verb influence.

Incorrect Correct
  Her speech influenced on my opinion.
  Her speech influenced my opinion.
  Social media influences on young people strongly.
  Social media influences young people strongly.
Tip: 

Influence works directly with the object and does not require on after the verb.

These verbs describe different sides of communication.

Incorrect Correct
  I implied from his tone that he was upset.
  I inferred from his tone that he was upset.
  Her comments inferred that something was wrong.

Tip: 

Imply = the speaker suggests something; infer = the listener understands or concludes something.
