Words that double the final consonant bofore adding suffix?

You're asking about the doubling rule in English spelling! Here's the breakdown:

When do we double the final consonant?

We double the final consonant of a word before adding a suffix (like -ing, -ed, -er, -est) if:

1. The word is one syllable:

* Example: "hop" becomes "hopping", "run" becomes "running"

2. The word is stressed on the last syllable, and has two syllables:

* Example: "begin" becomes "beginning", "admit" becomes "admitted"

3. The final consonant is preceded by a single vowel:

* Example: "stop" becomes "stopping", "plan" becomes "planned"

Exceptions:

* Words ending in -w, -x, or -y do not double the final consonant:

* Example: "saw" becomes "sawing", "fix" becomes "fixing", "try" becomes "trying"

* Words ending in -c before adding a suffix starting with -e or -i, change the -c to -ck:

* Example: "picnic" becomes "picnicking", "panic" becomes "panicked"

Here are some common examples of words that double the final consonant:

* -ing: hopping, running, stopping, planning, hitting, begging

* -ed: hopped, planned, admitted, begged

* -er: runner, swimmer, hitter, planner

* -est: smallest, biggest, hottest, fastest
