How to add -ING to a verb
- General rule : add -ING to the base form
talking / sing => singing / read => reading
1. When the base form ends in the vowel E , simply delete the letter:
dance => dancing / smile => smiling
If the verbs ends in -ee / -ye / *oe , no change: see => seeing / dye => dyeing / toe => toeing
lie => lying , die => dying
2. When the base form ends in -IE , the two vowels are replaced by Y .
lie => lying The cat is lying by the fire.
3. Verbs with one syllable and ending with 1 consonant+ 1 vowel + 1 consonant have 2 final consonants:
sit => sitting dig => digging swim => swimming knit => knitting
4. Same rule with the verbs with 2 or more syllables, but only if the last syllable is stressed.
--- for get => forgetting , --- listen => listening
