-ing Form and Present Continuous

1. The -ing form (present participle)

The -ing form is the verb with -ing at the end. It is used in the present continuous and in other structures (like I'm interested in learning).

1.1. Regular spelling rules

• Most verbs: base verb + -ing
  work → working, play → playing, read → reading
• Verbs ending in -e: drop the final e and add -ing
  make → making, write → writing, drive → driving
• Verbs ending in consonant + -y: just add -ing (do not change y)
  study → studying, carry → carrying

1.2. Doubling consonants (CVC pattern)

Sometimes we double the final consonant before adding -ing.

Basic rule (American English):

• The verb has only one syllable.
• It ends with consonant + vowel + consonant (CVC).
• The last consonant is not w, x, y.

Then we double the final consonant:

• stop → stopping
• sit → sitting
• run → running
• get → getting

Do NOT double w, x, y:

• snow → snowing (NOT “snowwing”)
• fix → fixing (NOT “fixxing”)
• play → playing (NOT “playying”)

1.3. Two-syllable verbs (summary)

In American English, we usually double the final consonant only when the stress is on the last syllable:

• begin → beginning (stress on gin)
• prefer → preferring (stress on fer)

But we usually do not double if the stress is on the first syllable:

• open → opening (NOT “oppening”)
• visit → visiting (NOT “visitting”)

1.4. Verbs ending in -ie

Verbs ending in -ie: change -ie → -y and add -ing.

• lie → lying
• die → dying
• tie → tying

2. Form of the present continuous

The present continuous (also called present progressive) is formed with:

am / is / are + -ing form of the verb

• I am working.
• You / we / they are working.
• He / she / it is working.

3. Affirmative forms

3.1. Full (uncontracted) forms

• I am studying.
• You are reading.
• He is cooking.
• She is playing the piano.
• It is raining.
• We are watching TV.
• They are working.

3.2. Contracted forms (very common)

• I am → I’m
• You are → you’re
• He is → he’s
• She is → she’s
• It is → it’s
• We are → we’re
• They are → they’re

• I’m studying.
• You’re reading.
• He’s cooking.
• She’s playing the piano.
• It’s raining.
• We’re watching TV.
• They’re working.

4. Negative forms

4.1. Full (uncontracted) forms

• I am not working.
• You are not listening.
• He is not sleeping.
• She is not studying.
• We are not cooking.
• They are not playing.

4.2. Contracted forms

• am not → (no common contraction in standard English; usually “I’m not”)
• is not → isn’t
• are not → aren’t

• I’m not working.
• You aren’t listening. / You’re not listening.
• He isn’t sleeping. / He’s not sleeping.
• She isn’t studying. / She’s not studying.
• We aren’t cooking. / We’re not cooking.

5. Interrogative (question) forms

Structure: Am / Is / Are + subject + -ing form + ... ?

• Am I doing this right?
• Are you working today?
• Is he studying English?
• Is she watching TV?
• Is it raining?
• Are we leaving now?
• Are they coming?

6. Negative interrogative forms

Two common patterns:

6.1. Full (uncontracted)

• Am I not doing this right?
• Are you not working today?
• Is he not studying?

6.2. Contracted (very common)

• Aren’t you working today?
• Isn’t he coming?
• Isn’t she sleeping?
• Aren’t they leaving now?

7. Main uses of the present continuous

• Actions happening now (at the moment of speaking)
  • I’m talking to you right now.
  • She’s reading a book at the moment.
• Temporary actions or situations
  • He’s living with his parents this month.
  • They’re working on a new project.
• Plans and arrangements for the near future
  • We’re meeting them tomorrow.
  • I’m flying to Boston next week.
• Changing situations
  • The weather is getting colder.
  • More people are using electric cars.

8. Verbs that usually do not use the present continuous

Some state verbs (non-action verbs) usually do not use the present continuous: for example know, like, love, hate, believe, understand, want, need.

• Correct: I know the answer. (NOT “I’m knowing the answer.”)
• Correct: She likes chocolate. (NOT “She’s liking chocolate.”)
