Correct spelling, explanation: the word should comes from Old English scholde. The first thing to notice is ch – back then it was read more like h, which is why the spelling has adapted in this way. O became ou when the whole vowel system was changed to unify the English spelling in the 15th century. And while the l in should is silent, it can’t be omitted.

2. used to indicate a probability

Incorrect spelling, explanation: technically, the pronunciation of shoud could work, but should is the correct spelling. The word has evolved from the Old English scholde, and changed quite a bit in order to adjust the spelling to the pronunciation, but the structure of the word is still recognizable. If you ever struggle with the spelling of should, and you wonder whether to include the l or not, think of a word belonging to the same family: shall, and it should help you out!
