Suffix is such an ending that gives a different meaning to the root words to which one add suffixes. It is added or affixed to the end of a word. Suffixes are used to make a Noun, Adjective and Adverb. Different rules are applied while adding a suffix to a word.
Before a Suffix beginning with a Vowel (Single syllable root words):
Double the consonant at the end of a single syllable word when the last Consonant is preceded by a Vowel. E.g: BaT: Batted, Batter, Batting
Other such words: Bed, Beg, Clap, Clip, Drop, Fat, Fit, Glad, Hit, Hop, Quit, Rub, Run, Sad, Ship, Sip, Sit, Skip, Slap, Slip, Squat, Stop, Tap, Ton, Trap, Trek, Sip.
Exceptions: (Where consonant remains single)
Effects of vowel preceding consonant
Whether the consonant at the end of a root stays single or double often depends on whether a vowel is preceding is pronounced long or short.
Whether the Consonant is W, X or Y.
If the last consonant happens to W, X or Y and it is preceded by a Vowel, the last consonant remains single despite the rule.
Some such words: Saw, Stew, Tow, Tax, Vex, Stay, Toy, Try.
Where the Consonant is preceded by Two Vowels:
Here also the consonant remains single though the last consonant is preceded by Vowel. E.g.: Beat, beater, beating.
Other such words: Boat, Creep, Droop, Group, Haul, Heap, Heat, Hoot, Leap, Loop. Sail, Seal, Sleep, Soap, Soar, Treat, Trail.
If a vowel happens to be U with Q beginning the single Vowel rules applies and the last consonant is doubled. The U after Q is not counted as a vowel (A part of a Digraph) as it only adds to the Q sound. E.g. Quit: Quitting. Quiz: Quizzed, Quizzing.
Where there two Consonant at the end of a Root word:
The last consonant does not double. For example: Fast, Halt, Turn.
