Suffixes

из English Grammar Today
A suffix is a letter or group of letters added at the end of a word which makes a new word.
words
suffix
new words
forget, use
-ful
forgetful, useful
state, govern
-ment
statement, government
complicate, create
-ion
complication, creation
The new word is most often a different word class from the original word. In the table above, the suffix -ful has changed verbs to adjectives, -ment, and -ion have changed verbs to nouns. If you see a word ending in -ment, for example, it is likely to be a noun (e.g. commitment, contentment).
Suffixes: spelling
Often, the suffix causes a spelling change to the original word. In the table above, the -e ending of complicate and create disappears when the -ion suffix is added. Other examples of spelling changes include:
beauty, duty + -ful → beautiful, dutiful (-y changes to i)
heavy, ready + -ness → heaviness, readiness (-y changes to i)
able, possible + -ity → ability, possibility (-le changes to il)
permit, omit + -ion → permission, omission (-t changes to ss)
A good learner’s dictionary will give you information on the correct spelling of words with suffixes.
