Suffixes: IBL vs AL

The video tutorial explains the use of suffixes 'IBL' and 'A' to form adjectives, often from verbs. It provides a general rule: use 'A' if the base word is complete on its own, like 'Dependable'. Exceptions to this rule are discussed, such as 'accessible' and 'digestible', which use 'IBL' despite having complete base words. The tutorial emphasizes the importance of visual checks for correct spelling and notes that 'A' is more frequently used and productive for creating new words.
