Comparatives, Superlatives & First Conditional

We use the comparative form of an adjective to compare two people or things. For short adjectives we add -er and use 'than' (Tom is taller than Sam; this box is bigger than that one), and for long adjectives (two or more syllables) we use 'more' before the adjective (English is more interesting than maths). We use the superlative form to compare three or more things, adding -est with 'the' for short adjectives (the tallest boy) or 'the most' for long adjectives (the most expensive car). Some adjectives are irregular and do not follow the rules: good becomes better and best, and bad becomes worse and worst (Ali is a better runner; today is the worst day). When two things are equal, we use 'as + adjective + as' (she is as tall as her sister). We also use the first conditional to talk about a real future possibility: the 'if' clause uses the present simple and the main clause uses 'will' + base verb (If it rains, we will stay at home; you will pass if you study). For example: 'This is the biggest shop in town, and if you go early, you will find better prices than in the small shops.'
