3. The Doubling Rule
shop (base word)
shop + ed = shopped
shop + ing = shopping
The last consonant in shop, p, was doubled before
the endings were added. This happens in short-
vowel words such as shop that end in just one
consonant.
If a one-syllable word ends with one vowel and
one consonant, double the final consonant.

4. Dropping Rule
like (base word)
like + ed = liked
like + ing = liking
The e was dropped before these endings were
added. This happens if a base word ends with
e, and the ending starts with a vowel.
If the base word ends with a sneaky e, drop the e
and add –ed or –ing.
