bored and board

Just saw this one and thought to myself, "What is so exciting about a board?"

bored: feeling unoccupied or lacking interest in activity

board: (n) a long, flat piece of wood; (v) to get on or into

I am bored of this board. Let's board the ship.

clothes and close

This one makes me laugh every time I see it!

clothes: items worn to cover the body

close: (v) move or cause to move; (adj) a short distance away; (n) the end of an event

Close the box of clothes and place it close to the entrance so the postman will know to pick it up even after we close the shop.

regardless and irregardless

regardless: without paying attention to the present situation

irregardless: is not a word — don't use it

Regardless of the facts, people continue to believe that "irregardless" is an actual word.

whether and weather

It is flooding in Cedar City, Utah which is the town I claim as my home (although I was born in Montana).

whether: a conjunction expressing an inquiry or investigation, a doubt, or choice

weather: (n) the state of the atmosphere; (v) wear or change in the appearance or texture

I don't know whether the weather will weather my swede jacket, but I'll take my chances anyway because I enjoy the rain.
