Common mistakes'Conventional' is sometimes confused with 'conventionally.', Learners may think it means outdated instead of traditional., Use with a noun, not as a standalone adjective.Confusing with 'customize', which means to modify., Using 'customary' inappropriately for uncommon practices., Mixing up with 'habitual', which implies personal habits rather than societal norms.'Ordinary' confused with 'extraordinary' — they are opposites., Using 'ordinary' to describe positive experiences may seem negative., Misusing 'ordinary' as a verb.Confusing 'standard' with 'standards' (plural), Using 'standard' as a verb incorrectly, Misplacing the emphasis in pronunciationConfused with 'typical' vs 'typical of', which has a slight distinction in usage., Using 'typical' too broadly, when more specific adjectives could be appropriate.
Usage notesUse 'conventional' for things that are considered usual. It's appropriate in formal writing but can be used in everyday conversation.Use 'customary' when describing behavior or practices that are widely accepted; it’s neutral but may sound slightly formal in casual contexts.Use 'ordinary' to describe things that are normal or average.
