Comparatives and superlatives help us describe differences. For short adjectives, add -er and -est: 'The new office is bigger and brighter than the old one.' For longer adjectives, use more and most: 'Working from home is more convenient but less social than the office.' Irregular adjectives have special forms: good → better → best, bad → worse → worst. To show equal comparison: 'Option A is as cheap as Option B.' To show a difference in degree: 'The new software is considerably more reliable than the previous version.' And to contrast two things: 'The morning shift is busier than the evening shift, whereas the afternoon is the quietest period.'

💡 Did you know? The longest superlative in standard English is 'most incomprehensible'. The shortest superlative is 'best'. Native speakers use comparatives and superlatives thousands of times every day without thinking about the rules.
