Adding a prefix to a word doesn't usually change the spelling of the stem of the word.
For example:-
anti + septic
antiseptic
auto + biography
autobiography
de - sensitize
desensitize
dis - approve
disapprove
im - possible
impossible
inter - mediate
intermediate
mega - byte
megabyte
mis - take
mistake
micro - chip
microchip
re - used
reused
un - available
unavailable
Adding a suffix to a word often changes the spelling of the stem of the word. The following may help you work out the changes. Again there are exceptions, so if you're not sure - look it up in your dictionary.
Words ending in a consonant
When the suffix begins with a consonant, just add the ending without any changes.
For example:-
treat + ment
Treatment
Doubling the consonant
For most words with a short vowel sound, ending with a single consonant, double the consonant when adding a suffix that starts with a vowel, such as er, ed or ing.
For example:-
mop + ing
mopping
big + est
biggest
hot + er
hotter
For words endling in l after a vowel, double the l before adding er, ed or ing.
For example:-
carol + ing
carolling
travel + er
travelling
Exceptions: Some words ending in r, x, w or y are exceptions to the doubling rule
tear + ing
tearing
blow + ing
blowing
box + er
boxer
know + ing
knowing
And if your main word has two consonants at the end, or more than one vowel, don't double the consonant.
rain + ing (two vowels a + i)
raining
keep + er (two vowels e + e)
keeper
break + ing (two vowels e + a)
breaking
hang + er (two consonants n + g)
hanger
Word Endings
Words ending in ce and ge
When you want to add a suffix starting with a or o leave the e in.
For example:-
manage + able
manageable
notice + able
noticeable
courage + ous
courageous
Exceptions:
prestige + ous
prestigious
Words ending in ie
When you want to add ingto verbs ending in ie, drop the e and change the i to a y.
For example:-
die - dying lie - lying tie – tying
Words ending in y after a consonant
When you want to add suffixes such -as, -ed, -es, -er, -eth, -ly, -ness, -ful and -ous to a word ending in y after a consonant, change the y to an i before adding the suffix.
For example:-
eighty + eth
eightieth
duty + es
duties
lazy + ness
laziness
mystery +ous
mysterious
beauty + ful
beautiful
multiply + ed
multiplied
busy + ly
busily
Words ending in y after a vowel
Keep the y when adding suffixes such as er, ing or ed.
For example:-
destroy
destroying
destroyed
pry
prying
pried
buy
buying
buyer
play
playing
Player
You may be confused by some differences in spelling that are actually caused by the differences between American (AmE) and British (BrE) English spelling. It's not that one is right or better and the other wrong or worse, the trick is to learn one form of spelling and stick to it. Try not to mix them up.

1 - When used to talk about roads and motorways. Someone I know took over 4 hours to complete a 25 minute drive, because he didn't know what his sat nav system meant when it said "Take the ramp".
2 - When a Brit hears the word "yard" in connection with houses, we think of a concrete area, usually full of building materials, or work tools.
3 - Bank holidays have to follow certain rules, otherwise they are also known as public holidays in the UK. You can read more about what makes a bank holiday in the British Culture section.
!Note - *if the sink is in the kitchen - it's a sink, but if it's in the bathroom it's a basin.
Another huge difference that causes great confusion is writing the date. When you write the date in numbers British and American English differ. To write the date 7th of September 2007 a Brit would write dd/mm/yy (07/09/07) and an American would write mm/dd/yy (09/07/07). This often causes great confusion. It's better to write the date in full (7th September 2007 or September 7th 2007). It also looks nicer.
