Demolish v. destroy- Demolish is only used for buildings (and sometimes in sport), destroy can be used for lots of things Dwindle v. decrease- Dwindle implies that the decrease is slow and gradual, decrease can be fast or slow, gradual or sudden Adore v. worship- When used for religious things, they mean the same, but when used for people, adore means love very much while worship means to treat like a god Expedition v. safari- Safari describes an expedition, usually in Africa, focussed on wildlife hunting or spotting, whereas an expedition can also describe mountain treks or other things unrelated to Africa or animals Vertical v. perpendicular- Vertical means up and down, whereas perpendicular just means at right angles to: perpendicular to horizontal is vertical, but perpendicular to vertical is horizontal All of these words, as tensai said, are very similar, and no-one will much notice if you get it wrong, but these are the differences between them. Hope that helps!
