Tie or Tide

I think that I have been using an expression incorrectly my entire life. If I had an afternoon snack, I would say that this will tie me over until dinner. I believe that the phrase is actually this will tide me over until dinner. The word tide here makes no sense to me. When I think of tide, I picture water, the ocean or laundry detergent. This expression really can’t be tide, can it?



I promise to have information about my Seattle trip soon.
