il– is used before a word beginning with ‘l’ {e.g. illiterate, illegal…}
-
ir– is used before a word beginning with ‘r’ {e.g. irregular, irrelevant…} What does the prefix ir mean? The prefix ir means ‘opposite of’ or ‘not’

There are no rules for in– , un– and dis–
- We can also use the prefixes un– and dis– with verbs to form their opposites. (e.g. untie, unfasten, unpack, undo, unlock, undress, disagree, disappear, dislike, disqualify, disobey, disconnect etc.)
- dis meaning (with adjectives, adverbs and nouns): The prefix dis- in adjectives, adverbs and nouns mean ‘not’ or ‘opposite of’ (dishonest, disagreeably, disadvantage)
- in prefix meaning (meaning of the prefix in-) (in prefix): The prefix in means ‘not’ or ‘opposite of’ (in prefix words: incorrect (= not correct), infinite, inaccurate, inactive, inadequate, incapable, incoherent, incomplete, indirect…) (words with the prefix in)

Word formation suffixes
What is a suffix in English? /What does suffix mean? / Suffix meaning formation?
A suffix is the letters or syllables that we add to the end of a word to create new words. Using suffixes to form new words is a good way to enrich your vocabulary.

As we said before, we add prefix or suffix to make new words. Knowing the different suffixes can enable you to guess the meaning of new words and recognize whether the word is a verb, a noun, an adjective, an adverb, etc.
The suffix can change the spelling of the original word. For example, the -e ending of the verb ‘create’ and the adjective ‘wise’ is omitted when the suffix is added.
- Create → creation
- wise→ wisdom
Adding the suffixes change the spelling of the original word.
In the English language, not only do suffixes change the spelling of the original word but they also change the word’s part of speech. For example, the suffix ly changes adjectives to adverbs. (brave (adjective) → bravely (adverb), correct → correctly )
Here is a list of common suffixes (suffixes list/suffix examples)

Suffixes tips:
- The suffix less meaning (less definition): The suffix less means ‘without’.
- al suffix meaning: The suffix al in adjectives means ‘having the quality of’ or ‘connected with’. The suffix al in nouns means ‘the state or process of’
- able suffix meaning: The suffix able means ‘that can or must be’ or ‘having the quality of’
The table below displays more suffixes with meaning and examples (suffix words)
