Ending -ing

Mastering the ‑ing form of verbs is essential for English language learners. This form, known as the present participle or gerund, is used in various grammatical structures, such as continuous tenses, and as a noun. While simply adding ‑ing to a verb is the general rule, there are specific spelling changes that depend on the verb's ending. Let's break down the rules for adding ‑ing to verbs, with clear examples for each case.

How to form

Rule 1: Just add -ing

For most verbs, you simply add ‑ing to the end of the base form. This is the most common and straightforward rule.

  • walk → walking
  • talk → talking
  • play → playing
Rule 2: Dropping silent -e

If a verb ends in a single, silent ‑e, you must drop the ‑e before adding ‑ing. This rule helps maintain the correct pronunciation and spelling.

  • make → making
  • take → taking
  • write → writing
Exception: If the verb ends in ‑ee, ‑ye, or ‑oe, you do not drop the ‑e and just add ‑ing.
  • see → seeing
  • dye → dyeing
  • hoe → hoeing
Rule 3: Verbs ending in ‑ie

If a verb ends with ‑ie, change the ‑ie to ‑y and add ‑ing.

  • lie → lying
  • die → dying
  • tie → tying
Rule 4: Verbs ending in ‑ic

If a verb ends in ‑ic, change it to ‑ick before adding ‑ing.

  • panic → panicking
  • traffic → trafficking
  • mimic → mimicking
Rule 5: Doubling the final consonant

If a verb ends in consonant + vowel + consonant (CVC), and the last syllable is stressed, double the final consonant before adding ‑ing.

  • prefer → preferring
  • regret → regretting
  • run → running
Do not double if the stress is not on the last syllable.
  • visit → visiting
  • happen → happening
  • develop → developing
Exception: This rule does not apply if the final consonant is ‑x, ‑y, or ‑w.
  • fix → fixing
  • play → playing
  • snow → snowing
