I once had a problem spelling correctly words like perceive, believe, deceive, retrieve, ceiling etc.
The problem was with the placement of "ei" and "ie". I know some of u still do.
Guessing when and with which word letter 'e' comes b4 letter 'i' and vice versa.
Now, no more guess folks. If the word you want to spell or type has letter 'c' like perceive, receive, conceits, conceive etc. Letter 'e' will come b4 'i'.
When there is no letter C b4 those two letters in the word u want to type or spell, Letter 'i' will come b4 letter 'e'. Eg, believe, thief, retrieve, field, shield, niece. Etc.
Exceptions: foreigner, leisure, either, neither, height, weight.
