This presentation introduces the main structures used to compare people and things. It begins with equality and inequality using as … as, then explains how comparative forms show differences and how superlatives identify the highest or lowest degree within a group.

The lesson distinguishes the endings used with shorter adjectives from the more, less, most, and least forms used with longer adjectives. It also provides reference tables with regular and irregular forms.

Important points

• Use as + adjective + as to compare equal qualities, and add not to show inequality.
• Shorter adjectives commonly form comparisons with -er + than.
• Longer adjectives commonly use more or less + adjective + than.
• Shorter adjectives commonly form superlatives with the + adjective-est.
• Longer adjectives commonly use the most or the least + adjective.
• Some adjectives have irregular forms, including good, better, best and bad, worse, worst.
